Despite the huge number of television antennas presented on the consumer market, which can be easily purchased at any electronics store, interest in how to make an antenna for a TV with your own hands does not disappear. This interest can be explained by a reluctance to spend money on buying an antenna, being away from retail outlets (if you are in the outback or at the dacha) or the failure of the purchased one.

Antennas for a television receiver can be divided into several types.

  1. All-wave antenna– the design is easy to manufacture; it can be made from simple available materials. It picks up a digital signal quite well outside the city, where there is not much interference. When located near a broadcast tower, it can receive analog television.
  2. Log-periodic band antenna also easy to make. It has perfect consistency with the feeder across all ranges, without changing its parameters. Since this design has average technical parameters, it can be used in the country, or as an indoor antenna in the city.
  3. UHF antenna. A simplified modification of the Z-antenna is often used; it works well, regardless of the signal reception conditions.

All-wave antenna

All-wave TV signal catchers are also called frequency independent (FIN). Their designs can be different.

Of two petals

The figure shows an all-wave antenna made from two metal plates triangular in shape and two wooden slats on which copper wire is stretched in the shape of a fan.

Copper wire can be taken of any diameter, it does not play a special role. The ends of the wire are attached at a distance of 20 to 30 mm from each other. The plates with the other ends of the wire soldered together should be located at a distance of 10 mm from each other.

The metal plate can be replaced with a square piece of fiberglass, which has copper foil on one side.

Since the design of the homemade antenna is square in shape, its height will be equal to its width, and the angle between the panels will be 90 degrees. Zero potential point marked in yellow in the figure. There is no need to solder the cable braid in this place - tying it tightly will be enough.

A television signal receiver assembled in this way in the form of two lobes is capable of receiving both all decimeter channels and meter ones. Moreover, it picks up signals well in all directions. But if you install the CNA in an area of ​​poor signal reception from a TV tower, it will only work normally with amplifier. Others can also be used.

Butterfly shaped

You can make a television antenna in the shape of a butterfly with your own hands. To make this fairly powerful antenna yourself, you need to prepare a board or plywood with dimensions of 550 x 70 x 5 mm, a wire with a copper core with a cross-section of 4 mm, and, accordingly, a PK75 cable.

  1. Mark the holes on the plywood and drill them. Dimensions in the picture are in inches. Below the figure is a table for converting inches to mm.


  2. From copper wire you need to cut 8 pieces of the same length, 37.5 cm each.
  3. In the center of each wire, clear sections of insulation (2 cm each), as in the figure.

  4. After this, you should cut off 2 more pieces of wire, already 22 centimeters each, divide them into 3 equal parts and remove the insulation at the separation points.

  5. Give the segments V-shape. You should be careful to maintain a distance of 7.5 cm between the ends of the wire. This is the optimal distance to receive a clear signal.

  6. Connect all the elements according to the figure below.

  7. Next, you need to purchase a socket to connect the plug to it.
  8. The cable must be soldered to the coil contacts, as in the figure.

  9. Make 2 more pieces of wire of the required length to connect the antennae to the socket.
  10. Screw the socket onto the board and connect all the elements.


That's all - you have made an antenna for your TV with your own hands.

From beer cans

To make such an original ChNA you will need 2 cans (0.5 l or 0.75) of beer or other drink. But before you make a television antenna, you need to consider some material requirements. Namely, it is recommended to purchase a high-quality television cable with a resistance of 75 ohms per meter. Which is correct? Make sure that the central core is strong and that the braid is double and continuous.

Don’t forget, the longer the cable, the stronger the signal attenuation will be, which is especially important for receiving meter waves, in contrast to UHF, for which the length of the wire also matters, but not so much.

It will also be necessary to prepare the usual wooden trempel, a couple of self-tapping screws, electrical tape or tape and, if possible, a soldering iron with tin.

An antenna made from beer cans can receive both the UHF and meter wavelengths.

To illustrate the entire process, you can watch the video.

Log-periodic antenna

A log-periodic antenna (LPA) can be used to receive radio waves in both the meter and decimeter ranges. To make such a signal receiver, you can use an aluminum tube with a diameter of 10 mm and metal rods (studs) as a stand, which can be purchased at a store that sells fasteners. Ideally, instead of threaded rods, it is better to use smooth tubes or rods. A plastic U-shaped box is used as a base.

When the soldering is completed, the manufacture of the device can be considered complete and you can begin testing your creation.

UHF antenna

Homemade decimeter signal catchers can have different shapes and designs, from the simplest to manufacture to more complex devices.

Ring-shaped

The simplest design for receiving UHF can be made in a short time with your own hands from scrap materials. All you need is a coaxial cable and a piece of plywood of the appropriate size.

Now all this needs to be assembled:

  • prepare a piece of coaxial cable (RK75) 530 mm long (a ring will be made from it);
  • also cut another piece of cable 175 mm long - this will be a loop;
  • make a ring (1), solder a loop (2) and a cable (3) to it, which connects to the TV;
  • secure it all to a plywood sheet and point the completed TV signal receiver towards the TV tower.

If your TV receiver uses such an antenna, try making a more complex device.

Figure 8

You can make your own home UHF antenna from wire in the shape of the number 8. To make such a receiver, you can use copper or aluminum wire with a diameter of 3 to 5 mm, as well as PK75 cable. During the manufacturing process you will also need glue gun

Manufacturing progress.

  1. Using wire cutters, you need to cut 2 pieces of wire 56 cm each.
  2. At the ends of each segment, make a loop, which should take 1 cm.
  3. Bend the wire squares and connect the loops. Solder the cable to the squares as shown in the picture. The central core is soldered to one square, and the braid to the other. The distance between the elements should be 2 cm. The entire structure can be secured in the lid of a 20 liter water bottle, filled with glue.

Such a UHF receiver can be placed anywhere, and it does not require an amplifier. Perhaps an amplifier may be needed if the device is outdoors and the cable length is significant. In this case, to compensate for signal losses, its installation will be required.

From a metal-plastic pipe

You can make a television antenna with your own hands from an ordinary metal-plastic pipe. This will result in a device for receiving UHF with a possible range from 480 MHz to 1000 MHz. This “model” uses a pipe with a diameter of 16 mm and a cable of 5.5 m. The ring will require 55 cm of pipe, and the stand will require 14 cm, which is equal to a quarter of the wavelength. This serves to better match the outer braiding of the cable and reduces high frequency currents.

The cable exit in this design is made through a hole in the pipe. The cable braid should be attached with a clamp to the stripped part of the pipe. The central core of the cable is attached to the ring (you can use a screw with a washer and a nut). This homemade product works well as an indoor antenna in apartments with reinforced concrete walls that do not transmit television waves well. Thanks to the extended cable, you can take it out onto the balcony or place it on the windowsill - the quality of reception will only improve.

In the form of a frame

Another UHF antenna design is assembled in the form of a frame. It will be made from aluminum plates(stripes).


Thus, home-made antennas will help you save money on purchasing them, and in some cases get out of the situation where you have a TV, but the standard antenna is out of order, or it doesn’t exist at all. Moreover, the quality of reception of homemade products is no worse than their factory counterparts. If you do not want to make the device yourself, then the information in the store will be useful to you.

Despite the rapid development of satellite and cable television, the reception of terrestrial television broadcasts still remains relevant, for example, for places of seasonal residence. It is not at all necessary to buy a finished product for this purpose; a home UHF antenna can be assembled with your own hands. Before moving on to considering the designs, we will briefly explain why this particular range of the television signal was chosen.

Why DMV?

There are two good reasons to choose designs of this type:

  1. The thing is that most channels are broadcast in this range, since the design of repeaters is simplified, and this makes it possible to install a larger number of unattended low-power transmitters and thereby expand the coverage area.
  2. This range is selected for digital broadcasting.

Indoor TV antenna “Rhombus”

This simple, but at the same time, reliable design was one of the most common in the heyday of on-air television broadcasting.

Rice. 1. The simplest homemade Z-antenna, known under the names: “Rhombus”, “Square” and “People’s Zigzag”

As can be seen from the sketch (B Fig. 1), the device is a simplified version of the classic zigzag (Z-design). To increase sensitivity, it is recommended to equip it with capacitive inserts (“1” and “2”), as well as a reflector (“A” in Fig. 1). If the signal level is quite acceptable, this is not necessary.

The material you can use is aluminum, copper, and brass tubes or strips 10-15 mm wide. If you plan to install the structure outdoors, it is better to abandon aluminum, since it is susceptible to corrosion. Capacitive inserts are made of foil, tin or metal mesh. After installation, they are soldered along the circuit.

The cable is laid as shown in the figure, namely: it did not have sharp bends and did not leave the side insert.

UHF antenna with amplifier

In places where a powerful relay tower is not located in relative proximity, you can raise the signal level to an acceptable value using an amplifier. Below is a schematic diagram of a device that can be used with almost any antenna.


 Rice. 2. Antenna amplifier circuit for the UHF range

List of elements:

  • Resistors: R1 – 150 kOhm; R2 – 1 kOhm; R3 – 680 Ohm; R4 – 75 kOhm.
  • Capacitors: C1 – 3.3 pF; C2 – 15 pF; C3 – 6800 pF; C4, C5, C6 – 100 pF.
  • Transistors: VT1, VT2 – GT311D (can be replaced with: KT3101, KT3115 and KT3132).

Inductance: L1 - is a frameless coil with a diameter of 4 mm, wound with copper wire Ø 0.8 mm (2.5 turns must be made); L2 and L3 are high-frequency chokes 25 µH and 100 µH, respectively.

If the circuit is assembled correctly, we will get an amplifier with the following characteristics:

  • bandwidth from 470 to 790 MHz;
  • gain and noise factors – 30 and 3 dB, respectively;
  • the value of the output and input resistance of the device corresponds to the RG6 cable – 75 Ohm;
  • the device consumes about 12-14 mA.

Let's pay attention to the method of power supply; it is carried out directly through the cable.

This amplifier can work with the simplest designs made from improvised means.

Indoor antenna made from beer cans

Despite the unusual design, it is quite functional, since it is a classic dipole, especially since the dimensions of a standard can are perfectly suitable for the arms of a decimeter range vibrator. If the device is installed in a room, then in this case it is not even necessary to coordinate with the cable, provided that it is not longer than two meters.


Designations:

  • A - two cans with a volume of 500 mg (if you take tin and not aluminum, you can solder the cable instead of using self-tapping screws).
  • B – places where the cable shielding is attached.
  • C – central vein.
  • D – place of attachment of the central core
  • E – cable coming from the TV.

The arms of this exotic dipole must be mounted on a holder made of any insulating material. As such, you can use improvised things, for example, a plastic clothes hanger, a mop bar or a piece of wooden beam of appropriate size. The distance between the shoulders is from 1 to 8 cm (selected empirically).

The main advantages of the design are fast production (10 - 20 minutes) and quite acceptable picture quality, provided there is sufficient signal power.

Making an antenna from copper wire

There is a design that is much simpler than the previous version, which only requires a piece of copper wire. We are talking about a narrow band loop antenna. This solution has undoubted advantages, since in addition to its main purpose, the device plays the role of a selective filter that reduces interference, which allows you to confidently receive a signal.


 Fig.4. A simple UHF loop antenna for receiving digital TV

For this design, you need to calculate the length of the loop; to do this, you need to find out the frequency of the “digit” for your region. For example, in St. Petersburg it is broadcast on 586 and 666 MHz. The calculation formula will be as follows: L R = 300/f, where L R is the length of the loop (the result is presented in meters), and f is the average frequency range, for St. Petersburg this value will be 626 (the sum of 586 and 666 divided by 2). Now we calculate L R, 300/626 = 0.48, which means the length of the loop should be 48 centimeters.

If you take a thick RG-6 cable with braided foil, it can be used instead of copper wire to make a loop.

Now let's tell you how the structure is assembled:

  • A piece of copper wire (or RG6 cable) with a length equal to L R is measured and cut.
  • A loop of suitable diameter is folded, after which a cable leading to the receiver is soldered to its ends. If RG6 is used instead of copper wire, then the insulation from its ends is first removed, approximately 1-1.5 cm (the central core does not need to be cleaned, it is not involved in the process).
  • The loop is installed on the stand.
  • The F connector (plug) is screwed onto the cable to the receiver.

Note that despite the simplicity of the design, it is most effective for receiving “digits”, provided that the calculations are carried out correctly.

Do-it-yourself MV and UHF indoor antenna

If, in addition to UHF, there is a desire to receive MF, you can assemble a simple multiwave oven, its drawing with dimensions is presented below.

To amplify the signal, this design uses a ready-made SWA 9 unit; if you have problems purchasing it, you can use a home-made device, the diagram of which was shown above (see Fig. 2).

It is important to maintain the angle between the petals; going beyond the specified range significantly affects the quality of the “picture”.

Despite the fact that such a device is much simpler than a log-periodic design with a wave channel, it nevertheless shows good results if the signal is of sufficient power.

DIY figure eight antenna for digital TV

Let's consider another common design option for receiving “digits”. It is based on the classic scheme for the UHF range, which, because of its shape, is called “Figure Eight” or “Zigzag”.


 Rice. 6. Sketch and implementation of the digital eight

Design dimensions:

  • outer sides of the diamond (A) – 140 mm;
  • internal sides (B) – 130 mm;
  • distance to the reflector (C) – from 110 to 130 mm;
  • width (D) – 300 mm;
  • the pitch between the rods (E) is from 8 to 25 mm.

The cable connection location is at points 1 and 2. The material requirements are the same as for the “Rhombus” design, which was described at the beginning of the article.

Homemade antenna for DBT T2

Actually, all of the examples listed above are capable of receiving DBT T2, but for variety we will present a sketch of another design, popularly called “Butterfly”.


The material can be used as plates made of copper, brass, aluminum or duralumin. If the structure is planned to be installed outdoors, then the last two options are not suitable.

Bottom line: which option to choose?

Oddly enough, the simplest option is the most effective, so the “loop” is best suited for receiving a “digit” (Fig. 4). But, if you need to receive other channels in the UHF range, then it is better to stick with “Zigzag” (Fig. 6).

The antenna for the TV should be directed towards the nearest active repeater, in order to select the desired position, you should rotate the structure until the signal strength is satisfactory.

If, despite the presence of an amplifier and reflector, the quality of the “picture” leaves much to be desired, you can try installing the structure on a mast.


In this case, it is necessary to install lightning protection, but this is a topic for another article.

How to make an antenna for a TV with your own hands so that it is not inferior in quality to a purchased device is a question that interests many home craftsmen and TV enthusiasts. There are various ways to make an antenna yourself, from the simplest designs to devices that receive satellite signals.

This option is suitable for people who want to install a regular indoor antenna at home or in the country for viewing federal channels. Anyone can construct such a device; no special knowledge is required.

This is the most basic method, so you only need copper wire 70–90 cm, thickness 2–3 mm. An indoor antenna is made as follows:

  1. Strip both ends of the copper wire.
  2. Attach one end to the battery, and insert the other into the TV connector.

The signal will appear immediately, and from 1 to 5 channels will be available to the user. With this simple method you can make a home antenna in 5 minutes.

The most popular way to make an antenna with your own hands from scrap materials. To make this you will need beer cans. Experts say that it will take no more than an hour to assemble an antenna from beer cans.

This is another easy option on how to make a TV antenna in a short time. The device picks up the signal well, providing high image quality.

All-wave antenna with amplifier

An all-wave antenna with an amplifier can be of different configurations. Its assembly takes more time than the first two options. But the advantage is that it is very powerful and receives all analog channels in excellent quality. One of the common options is the all-wave antenna of the “BUTTERFLY” shape.

Tools:

  1. Transformer.
  2. Foil.
  3. Glue.
  4. Roulette.
  5. Cardboard.
  6. Stapler.
  7. Marker.

DIY satellite dish

One of the most popular questions is, is it possible to make a satellite dish with your own hands? There are many videos on the Internet on how to make a dish for watching satellite television yourself.

This device can be made at home in two ways:

  1. Sticking on the matrix.
  2. Soldering mesh and wire.

The first manufacturing method is considered the most optimal and convenient. To do this, you need to make a drawing of the future device. The work must be approached very responsibly at this stage, all parameters must be calculated accurately, otherwise the output will be a device unsuitable for operation. The drawing draws a parabola, which is then transferred to a steel sheet. Its thickness should be 0.05 cm.

Stages of work

  1. Using a welding machine, make a steel frame with a diameter of 9–10 cm. The steel rods are turned to the outside, and the bearing is welded to the center.
  2. Install the resulting structure on a level place, and a pipe is attached to the installed bearing, then a knife is installed.
  3. Then the frame is filled with concrete and dried for 5 days.

At the final stage, it is necessary to glue the antenna; this can be done in different ways. To make work easier, it is recommended divide the structure into 8 parts. For gluing, fiberglass or epoxy primer is used.

Apply machine oil to the dry concrete form and insert the pipe into the washer. Afterwards, the homemade plate is covered with resin and the fiberglass is glued. The manufacturing process of the device is completed. Read also,.

This is a very simple and effective antenna for receiving digital and analogue television. Suitable for use both at home and outdoors. The antenna is a "bi-square" (double square) - this is the simplest and most popular design to replicate.
To build an antenna you will need very little:

  • - Coaxial cable.
  • - TV connector.
  • - Copper wire is about a meter long, with a diameter of 2 - 4 mm. Any one will do, even steel.
  • - Flux with solder.
  • - Plastic round junction box for the housing. Or any other.

Making an antenna for receiving digital television (DVB-T)

I will make an antenna to receive digital television channels. To begin manufacturing, you first need to calculate the dimensions of the future antenna. And to calculate the dimensions, you need to know the middle of the reception range of digital channels. The average frequency is approximately 690 MHz. If you want to make an antenna for analog channels, then take, say, 470 MHz for UHF, etc. (TV channel ranges can be viewed)
Next we go here -
Enter the frequency and press “CALCULATE” and see what L1 is equal to. L1 is the square arm for the antenna. In my case, for a frequency of 690 MHz it is approximately 105 mm. The required number has been found, nothing else is needed.
Now we proceed directly to the construction of the bi-square antenna. We measure out approximately 90 cm of thick copper wire and bite it off either with wire cutters or pliers.



Next, we straighten the wire with our hands, making it smooth without the waves that formed after winding it from the reel.
We measure four 10.5 cm segments in a row on this wire.



Then we bend the double square. The wire is thick and bends with difficulty, which is good - it will not bend from accidental influences.


We bite off the excess wire, leaving an allowance of about a centimeter in order to solder the closed circuit.


We clean the connection points and future soldering.


We solder the circuit with solder and flux. Here it is better to use a more powerful soldering iron, since thick copper wire is difficult to heat up.



We strip the television cable and solder it to the antenna as in the photo.



In principle, the antenna is ready for operation. I won't stop there and will make a body for the central part.
Here's what I need.


Since the round box is too deep, I cut off exactly half with a hacksaw.


Then I will melt the grooves for the antenna with a soldering iron. This can be done with the same hacksaw.


I fill the connections of the wires with the body and the soldering points with glue.


All is ready. I'll hang the antenna outside the window on a nail.

Watch the video on how to make an antenna for a TV

Sometimes a television antenna breaks down at the most inopportune moment, or it is simply not at hand. For example, during a trip to the country. In this case, the question arises of how to make an antenna for a TV with your own hands from what you have at hand.

Using a homemade transmitter, you can watch a limited number of channels. And the reception may be of lower quality than that of a purchased device. Still, knowing how to make an antenna yourself from available materials can come in handy. An antenna can be either simple or complex. The device will be able to receive almost all types of broadcasts.

Antenna types

Before you start making a TV antenna with your own hands, it is worth understanding the types and technical characteristics of television receivers.

Depending on the installation location, indoor and outdoor television receivers are distinguished. Indoor devices are effective only in areas with good signal reception. They are not suitable for country TVs. For rural areas and areas remote from the television repeater, outdoor television receivers are used.

Based on the type of signal amplifier, television receivers are either active or passive. Passive-type structures receive and amplify impulses due to their own geometry. They do not require power supply and do not introduce their own interference and noise into the signal they receive. Making a passive antenna yourself is the easiest way.

Active devices are equipped with a signal amplifier, which is powered from the mains. An active amplifier itself creates interference and distortion in the area of ​​reliable reception if a device that is too powerful or of poor quality is selected.

Broadcasting is carried out on meter or decimeter waves. To receive only meter or only decimeter broadcast bands, band television receivers are best suited. For example, for the transmission of digital terrestrial television DVB-T2 in our country, only the decimeter range is used.

A log-periodic, or all-wave, television antenna can receive waves in both the meter and decimeter ranges. This is a broadband design with 10 vibrators. The log-periodic device in terms of gain corresponds to a 3-4 element all-wave antenna.

Operating frequencies are limited by the largest and smallest vibrator in the receiver. It fits well with the feeder. Its gain does not change, so connecting to the feeder does not require balancing and matching devices.

A cable with a resistance of 75 Ohms enters the lower tube, exits at the end (which is directed towards the television center) and is connected by a braid to the end of the lower tube, and by a core to the end of the upper tube.

Externally and according to the principle of operation, a log-periodic television antenna consists of several channel-wave devices connected together. Moreover, each of them has its own vibrator, reflector and director. When a signal arrives, vibrators closest in size to half its wavelength are excited. Such television antennas are used to receive both digital and analogue broadcasts.

The wave channel type receiver has the simplest design, which can be quickly assembled from simple and affordable materials. It receives an analogue television signal near a television tower and a digital one outside large populated areas, where there is little interference.

We use beer cans

A do-it-yourself dacha antenna made from beer cans is the simplest and most affordable passive type design. It can be done quickly and without basic skills. At the same time, it copes well with receiving UHF broadcasts.

To assemble an antenna from beer cans you will need:

  • cable of sufficient length;
  • aluminum cans (for the simplest design, 2 are enough);
  • 2 bolts or self-tapping screws;
  • plug (F – connector) for connecting the cable to the TV;
  • electrical tape or tape;
  • a base made of wood or plastic for attaching cans (you can use wooden coat hangers).

The antenna circuit is simple:

  1. Each can is attached with electrical tape or tape to the base pin at a distance of 7 cm from each other.
  2. The cable is stripped on one side. They are spread out and attached to the rings of the cans or to screwed-in screws. It can also be soldered. A plug is attached to the free end.

This simplest design is suitable for installation both indoors and outdoors. When used externally, the jars are covered with a large plastic container with the neck and bottom cut off. The cable is pulled through a hole made on the side, which can be sealed using boiling water. The finished receiver is connected and configured through automatic channel search.

You can also make an analogue of a satellite dish with your own hands. For this purpose, use a simple umbrella. You will also need:

  • aluminium foil;
  • copper cable;
  • 1 tin can;
  • amplifier and power supply for it.

DIY TV antenna made from beer cans

Operating procedure:

  1. Measure the umbrella segments between the spokes and cut out elements corresponding to these dimensions from foil. They are sewn to the dome of the umbrella, covering its entire interior.
  2. A TV signal receiver is installed at the focal point of the metal grille. The amplifier will be a core from which 4 cm of braiding has previously been removed, and a cable screen that protects against interference.
  3. An oval is cut out of an aluminum can. A hole is made in the center of it, through which a bare wire is passed and a contact is soldered. To protect against oxidation and corrosion, the joint is covered with plasticine.
  4. The amplifier is powered through a cable.
  5. The receiver is attached to the handle of the umbrella with tape so that it does not touch the metal. This will protect you from interference and distortion. The junction must be sealed with plasticine.
  6. The power supply is placed next to the TV, and the antenna is turned towards the repeater.
  7. Channels are established by driving the dish until the best signal is obtained.

This antenna works best if the tower is located no further than 35 km from it.

We use wire

Another simple design is a homemade wire antenna. To make it, you can use copper or brass wire. These materials are resistant to oxidation.

The wire must be stripped of insulation from the ends. One of them is connected to the TV, and the other to the radiator of the heating system. The pipe is led to the roof - it will work as a signal amplifier. Such an antenna will be able to receive no more than 5 signals. The wire can be stretched onto the balcony and secured to a clothesline.

You can make a TV antenna from wire in another way. It will require:

  • 2 pieces of copper wire 3-4 mm wide and 1.8 m long;
  • a plate of plywood or metal measuring 15 by 15 cm;
  • amplifier (you can use old decimeter amplifiers);
  • electric drill;
  • TV cable;
  • iron pipe or fittings for making a mast;
  • bolts.

This copper wire antenna is assembled as follows:

  1. They make catchers by bending the wire in the shape of 2 diamonds with sides of 45 cm. This is the optimal frame length for such a device.
  2. The resulting diamonds are fixed on the base. To do this, holes are drilled at the fastening points, flattening the wire, and screws are screwed in.
  3. If a metal plate is used as a base, then a welding machine can be used to attach the catcher.
  4. We fix the amplifier in the center and connect the cable to it.

The easiest way to use a mast here is to use a metal pipe, which can simply be dug into the ground or attached to any suitable support. The antenna is fixed to the top of the mast, and the cable is pulled through it. The entire structure is painted to protect against corrosion.

Another popular TV receiver made of copper wire that you can make yourself is a small-sized antenna with an unusual “butterfly” shape. For external use, such a device is made of wire 2-4 mm thick, for internal use - 2 mm or thinner.

A frame is made to receive TV channels. Frame length – 500 mm, width – 200 mm. It is twisted so that 2 identical triangles are obtained, which are separated using wire cutters and soldered to the cable, leaving a 14 mm distance between the vertices. A plug is attached to the other end of the cable. The structure is taped with adhesive tape or electrical tape to a material with dielectric properties - wood, hard rubber, plastic.

Home digital HDTV device

A powerful antenna for a TV, capable of receiving a signal at 490 MHz, is made from a transformer, which is better to purchase, since it will not be easy to make it yourself. You will also need:

  • cardboard;
  • scotch:
  • foil;
  • stapler;
  • glue.

To make a television receiver, a diagram is used according to which all the parts are cut out of cardboard. The elements are covered with foil, bent and trimmed. It is best to first find a template and diagram through a search engine and print it out on a printer or copy it from a printed publication.

First you need to make a reflector about 35 cm long and cover it on one side with foil. In the middle, 2 rectangles of the same size are cut to attach the catcher.

The antenna is assembled from the prepared parts. Departing 35 mm from the reflector, butterfly-shaped elements are glued to the plate. They can be attached using a stapler. In the middle of each such element, a hole is made for the cable, to which a transformer is connected and a plug is attached.

Option for apartment

You can make an antenna for indoor use using any of the methods presented above.

Another simple option at home is made as follows.

A simple DIY frame indoor antenna is made from copper wire or cable with foil in the winding. The device not only receives television channels, but also serves as a selective filter against interference.

To calculate the size of the loop, you need to know the wave frequency for a given region. The length of the loop will be equal to the product of the coefficient (300 units) and the average frequency range.

Cut off the required amount of wire or cable, and if necessary, clean the edges. Make a loop out of it and solder the TV cable leading to the receiver. A plug is connected to it.

The structure can be hung or installed on a stand. This simple device, with accurate calculations, is most effective for digital television.

A reliable device for the home is a diamond-shaped antenna. It is the simplest representative of zigzag television receivers. To improve reception, it is equipped with capacitive inserts and a reflector.

The device is assembled from plates or tubes 1-1.5 cm wide made of brass, copper or aluminum. To make capacitive inserts, foil, tin or metal mesh is used, which is soldered around the perimeter. The cable is laid from the center and along one side, avoiding sharp bends. It should not leave the frame.
