Television, like 10 years ago, is quite popular. Despite the development of technology, the procedure for transmitting a television signal has remained the same. The need to install an antenna is always relevant. However, there are times when this device fails - then it becomes necessary to make it yourself.

Features of homemade antennas

Sooner or later, many owners of TVs come to mind the question of how to make a simple TV antenna on their own. Some people think that this is a difficult procedure, however, in practice, the opposite is true. To be able to watch television, antennas must have the following characteristics:

• the device must have a certain coefficient of directional protection, signal amplification, as well as getting rid of interference;
• the antenna must have an automatic setting of values without human intervention;
• to avoid phase distortion, the amplitude and frequency must be carefully determined.

The reasons for making a TV antenna yourself are as follows:

• the residential building is new, not mastered by providers;
• the premises are located far from the city and retail outlets;
• cable television was turned off due to professional work;
• the old structure has broken down, but there is no financial means for the new one.

According to professionals, a homemade antenna can perfectly cope with its functions when the building is located in a favorable area, and the manufacturing process is carried out correctly.

Tools and materials

Home craftsmen make antennas from various materials and improvised means. Excellent options for the production of a television device are tubes, rods, copper wire, foil. The above materials are characterized by pliability, they bend perfectly and keep their shape. You can also use all kinds of conductive metal products:

• wires;
• corners;
• rods;
• stripes.

Coaxial wires have the same properties as copper wires, however, they are much cheaper . In addition, coaxil is considered a fairly solid base for antennas. To save experts recommend using pieces of wires that are available at home.

Manufacturing methods

There are several options thanks to which you can make an antenna for a TV with your own hands at home. Almost every TV owner can make a powerful indoor or outdoor structure, with the help of which it will be comfortable to watch TV programs and series.

At home, you can quickly create a broadband, passive, active, decimeter antenna - a loop or other type of device for a summer cottage using improvised means, for example, electrodes.

From coaxial cable

You can simply and quickly make a channel receiver from a small piece of coaxial cable with your own hands. For work, you will need plywood for the base or other sheet material, electrical tape, a knife and a soldering tool.

Step-by-step instruction

• It is required to take a piece of coaxial cable of 53 centimeters and bend it into a ring . In this case, the edges must be open and fixed in this form on the plywood sheet.
• From a similar cable it is worth cutting off a piece that is 17.5 centimeters long for the second loop.
• After that you need connect cable and on its second base, install the connector that is necessary for the TV.

In the course of such simple actions, you will get a simple good antenna, which will be difficult to pick up signals with high quality. To improve its functionality, it is worth installing an amplifier unit.

Eight

A homemade device for receiving channels in the form of an eight is assembled in a few minutes. For this purpose, you will need a cardboard box, for example, a shoe box, an antenna cable, a plug, a knife, a soldering tool, tape, foil, glue. When making an antenna, it is necessary to carry out several stages:

• open the box and free it from dust and dirt, and then proceed to pasting;
• Smear the bottom of the box with a small layer of glue and glue it with foil;
• close the box and paste over it with tape so that spontaneous opening does not occur;
• on the cover it is worth fixing the pieces of the cable in the form of a figure eight and glue them with tape;
• in the center of the figure eight, the cable must be stripped and a pair of conclusions made from the metal braid for further connection of the channel receiver;
• cut off the conductor to connect the antenna to the TV, while the length of the cable must correspond to the distance from the installation site of the structure to the unit;
• one of the ends of the cord must be stripped in accordance with the connector, making it so that there is a screen output, and from the main core it is assembled through 10-20 millimeters of insulation;
• connect cable leads to figure eight;
• connect the connector from the TV to the other end.

Having carried out all the above measures, the antenna can be considered functional. G8 is an excellent alternative to satellite TV, as its picture is no worse.

Double and triple square

It will take some effort from the wizard to assemble the channel receiver in the form of a double and triple square. However, a properly assembled device will allow the reception of even the smallest television signals. The quality of the construction of TV programs is influenced by the distance from the TV tower, therefore, in this case it is worth observing the correct size.

To make an antenna in the form of a double and triple square, you will need pipes made of metal, for example, copper, brass, aluminum, and in this case, you can use rods.

It is also worth preparing a dielectric rod, wood base, wires. Depending on the pipe diameter, the design accepts a certain number of channels:

• 1-2 centimeters catches 1-5 channels;
• 0.8-1.5 centimeters - 6-12 channels;
• 0.3-0.6 centimeters is used for channels in the decimeter range.

Such an antenna has the form of 2 or 3 frames with the correct shape, which have different sizes. Here are the stages of manufacturing a channel receiver.

1. Bending pipes into quadrangles.
2. They are connected in the upper part by an arrow, consisting of a conductor, and in the lower part by a dielectric.
3. Installation of an outdoor antenna on a wooden base.
4. Separation of the cable and separation of the sheath to a separate terminal.
5. Connecting the cable to the channel receiver.
6. Sealing the second end for the antenna plug so that the transmission of TV channels is carried out.

After the high-quality implementation of all the above activities, the television antenna can be considered ready. The double and triple square design is ideal for outdoor installations.

From metal cans

A country TV antenna made of beer cans can be considered the simplest and most affordable passive design. The procedure for its manufacture does not take much time and can be carried out even without the presence of any skills. Despite the absence of difficulties in work and expensive materials, a device made of metal cans is capable of perfectly receiving decimeter broadcasting ranges.

To collect the antenna from beer cans, you will need the following materials and devices:

• long cable;
• cans of aluminum, a simple design usually consists of two;
• 2 self-tapping screws and the same number of bolts;
• the plug with which the cable will be connected to the TV;
• scotch tape or electrical tape;
• base made of wood, plastic, on which the cans will be attached.

Scheme of making a television device

1. Each of the cans must be attached to the base pin using tape . In this case, the distance between the banks should be about 7 centimeters.
2. The cable should be stripped from one side … After that, it is worth diluting and attaching it. You can solder the cable, and mount the plug to its free end.

This simple structure can be installed both indoors and outdoors.

If the antenna is external, it is recommended to cover it with a large plastic container. The cable should be passed through the hole on the side.

Then seal with boiling water. The channel receiver should be connected and configured through the autosearch of channels.

In the form of a frame

To become the owner of a home-made TV receiver in the form of a frame, you will need aluminum plates, a metal mesh to make a reflector, a few bolts, nuts, a cable, and a plug. When working, you cannot do without a drill, screwdriver and pliers. To make an antenna, it is worth performing the following activities:

• cut off strips of aluminum, drill holes for bolts at their ends;
• assemble the frame, and fasten the joints with an overlap;
• to prevent oxidation, it is recommended to cover the above points with varnish or paint;
• to certain points of the structure, it is worth attaching a cable that has antenna connectors;
• attach the frame to the reflector, while the antenna electrical circuit should not short-circuit;
• mount the channel receiver on the mast and position it in the required place.

Butterfly shape

This type of antenna contributes to the reception of high-quality channels, therefore it is all-wave. Making a homemade butterfly design can be a great alternative to a satellite dish. The independent process of its manufacture must be especially careful and precise . The device will include a board, pieces of copper wires with 4 mm cores.

First of all, the master will need to mark the board with future holes, and then drill them according to the scheme. Next steps:

• cut 8 pieces of wire of 375 millimeters each, 2 - to connect the wings of 220 millimeters required to connect to the socket;
• for the manufacture of an electrical contact, it is worth stripping the insulation of the segments;
• pieces of wire must be bent in bare areas;
• V-like ones must have equal sides with a distance between the ends of 75 millimeters;
• it is worth installing wire elements on a wooden board, fixing with self-tapping screws;
• the leads from the receivers should be mounted to the socket, having mounted a cable there that transmits signals.

The broadband antenna can be considered ready-to-use and can be installed indoors to receive TV signals.

Recommendations

Experts advise not to be afraid to make television antennas at home, since this procedure will not waste a lot of time and money. In order not to buy several factory antennas, you can try to make a more complex structure that will be able to reproduce high-quality signals in an unfavorable location of the home. Starting the manufacture of a TV receiver is one of the simplest options. More serious designs should be done by experienced craftsmen, since they imply the use of drawings and additional skills.
