Cable antenna for digital TV in 5 minutes
A super simple and super quick to make antenna from a coaxial cable for receiving digital television channels can be made with your own hands in about 5 minutes. For this you will need absolutely nothing except the cable itself. And this is the main advantage of this antenna.
You can't live without a TV now.
This design will definitely help you out, for example, when you have just moved into your home and have yet to install a cable or install a stationary 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, like a whip one. To make it, it will be enough to simply remove two insulations from the cable and everything will work. Of course, I agree with this, but the loop antenna that I will make from coaxial cable will have much greater gain, due to its directivity and resonant closed circuit.
This is what the version made from black cable looks like.
Now let's start making the antenna in order.All we need is less than half a meter of coaxial cable of any color. I took the white one.
We retreat 5 cm from the edge of the cable and remove the top insulation.
Next, remove the insulation from the central core.
Now we twist everything together neatly and tightly.
Then, from the edge with the insulation removed, we retreat 22 cm and cut out a 2 cm piece of the top insulation and the shielded wire from the hose, without touching the insulation of the central core.
Now we measure another 22 cm from the end of the cut and make a cut 1 cm wide only by removing the top insulation. We do not touch the cable shield.
Next, take the end of the cable from which we started. And we wrap it very tightly at the last cut, forming a circle of the antenna.
At this point, our antenna is ready for use. Of course, this is not necessary, but if you hang the antenna outside, it is better to insulate all exposed areas of the cable with electrical tape. You can also add a rigid frame, but this is optional.
We direct the antenna to a repeater or television tower. The direction can also be selected experimentally by rotating the antenna.
The best option would be to place it outside the window, since the walls of the house greatly dampen the high-frequency signal.
If you still don’t understand how to make an antenna from a cable, be sure to watch the video below or ask questions in the comments.

The test showed excellent results
