I have long wanted to do this experiment and compare the antenna of two beer aluminum cans with a purchased one. I didn’t fully believe in a homemade antenna, but the tests speak for themselves.
Let's start with how I made this antenna.
For rigidity, I took a wooden lath 15 cm long. Screwed to it
from the inside, two empty cans of under-beer at a distance of 1 cm from each other on ordinary self-tapping screws with a wide head. Banks used the most popular in terms of volume - now it is 0.45 liters.
He carefully made a small window with a clerical knife and through this window screwed the can to the piece of wood. Then he bent this window back.
The cable used a real TV. I cleaned out more veins and screwed them to the same screws. It will not work to solder to the banks, since it is aluminum, and there is no need.
Well, I didn’t fully believe in this idea and didn’t believe at least in any potential of this antenna. It took me only 4 minutes to assemble.
For clarity, I am testing it on a conventional digital set-top box and will be guided by its signal level scale (the signal level can be called up by double or triple pressing the "info" button).
And immediately I got a shock, the signal quality is at 100%. It is the quality that is responsible for the stability of the picture, and here such indicators are.
I moved the antenna to the windowsill and the level caught up with the quality. I moved the antenna in all directions for the length of the cable and the signal quality did not drop at all, the most stable signal that I have seen.
Compare with the factory
First, I put the factory antenna in the same place, level and quality in the orange zone, the picture crumbles into squares and the sound stutters.
When the antenna was moved to the windowsill, the situation improved, but the picture was still crumbling.
Remember a couple of years ago they made an antenna from a piece of wire 14 cm long? Maybe there is some truth in this, the length of the can is just close to this value.
As a result, a homemade antenna turned out to be much better than a factory one and is made in literally 5 minutes from scrap materials. Ideal as a temporary solution or an antenna for a summer residence.
Have you made an antenna from scrap materials? If yes, write in the comments how and which one.
If someone wants to repeat this homemade product and the text version is not enough for you, then here is a short video of the process:
