All people sometimes get bored with standard TV channels, and they plug in satellite dishes or cable TV, which entails extra costs. Most often, you have to pay for connecting a cable or a plate (an exception, except during promotions in a company) and pay every month to show you the programs. Sometimes the financial situation does not allow citizens to pay for such services. Here comes to the aid of knowledge of electronics and radio engineering. This review will talk about how to make an antenna for a TV with your own hands.
What you need to create an antenna
If you live in a line of sight from a television and radio tower, then the antenna that will be discussed is quite useful. An individual home-made design will be quite able to provide a fairly large number of TV channels, although not in such good quality. In order to answer the question of how to create an antenna for a TV with your own hands, you do not need particularly deep knowledge in radio engineering, and the materials for it are very simple and cheap. We will need: a copper wire with a diameter of two to three millimeters and a length of seventy centimeters, a piece of double-sided fiberglass, a half-meter coaxial television cable with a wave resistance of seventy-five ohms, as well as an F-plug. Such an antenna will quietly receive signals in the UHF range, and with a sufficiently powerful signal, meter wavelengths. As a copper wire, a single-core wire is well suited for laying electrical wiring.
Work with wires
In the process of finding the answer to the question of how to make an antenna for a TV with your own hands, you will need to deal with wires. In the event that there are several cables, then, carefully working with a knife, cut off one of the conductors along the groove, while trying not to damage the insulation, although this is not necessary at all - insulating materials will play a purely aesthetic role. Agree, the bare wire does not look very nice. In principle, a do-it-yourself antenna for a TV can be connected using an aluminum wire. But it is worthwhile to understand that it will have to be connected by a threaded connection to the board contacts on the matching transformer. It is important to remember that the mounting nut must not touch the transformer foil, otherwise use an insulating washer or cut the foil. In the event that the wire was left without insulation, for the sake of beauty and observing the rules of the interior, you can put a vinyl tube on it.
We shape our design
So that the antenna for the TV, made with your own hands, takes the form of a circle, a paint bucket or any other cylindrical object is quite suitable. It is important to remember that the diameter of the circle should be about two hundred and twenty millimeters, although this is not necessary, an error of a couple of millimeters does not play a role. To produce a matching transformer board is a rather difficult task when compared with previous work on this antenna. The circuit board is best made of fiberglass with a thickness of one and a half millimeters and dimensions of 25x30 millimeters.
Conclusion
On this, the question of how to make the antenna can be considered resolved. It remains only to put it in the right place and proceed to set up TV channels. Now, knowing what constitutes a design for showing television channels, you can independently answer the question of how to make an antenna for a radio with your own hands. Good luck watching TV with a new, independently made antenna!
