Antenna from a cable for digital TV in 5 minutes
A super simple and super fast to manufacture antenna from a coaxial cable for receiving channels of digital television can be made with your own hands in 5 minutes. For this you need absolutely nothing but the cable itself. And this is the main advantage of this antenna. Without a TV, nowhere.This design will surely help you out, for example, when you just moved into a dwelling and still managed to neither stretch the cable nor put a fixed antenna. Of course, this is not the only example where this truly simple loop antenna will help. Now in the comments, someone will definitely write that there are even simpler antennas, such as a whip. For the manufacture of which it will be enough just to remove two insulation from the cable and everything will work. Of course, I agree with this, but loop antenna,which I will make from coaxial cable will have a much greater gain, due to its directivity and resonantly closed loop.And now making the antenna in order. All we need is less than half a meter of coaxial cable of any color. I took white.From the edge of the cable, retreat 5 cm and remove the top insulation.Next, remove the insulation from the central core.Now everything is twisted together neatly and tightly.Then, from the edge with the isolation removed, we retreat 22 cm and cut a piece of 2 cm of the upper insulation and shielded wire with a fake one, without touching the central insulation cores. Now measure the end of the cut 22 cm and make a slot with a width of 1 cm only with the removal of the upper insulation. The screen of the cable is not touched.Then we take the end of the cable from which we started. And very tightly tie it up at the last cut, forming a circle of the antenna.
Making an antenna from a coaxial cableThis is a variant made of black cable.
Antenna locationAntenna is sent to a repeater or a television tower. The direction can be chosen experimentally by rotating the antenna. The best option is if you place it outside the window, as the walls of the house very much jam the high-frequency signal.
