Dual patch antenna, to fly all around you.

As you know, to have a good video signal range, you must use a patch antenna.
But with this antenna you can only fly before you and you can't fly behind you.
THE low cost SOLUTION:
Make a dual patch antenna.

sur la deuxième patch je ne prend que la plaque avant, le reste de l'antenne où il y a le câble je ne l'utilise pas.
Cette plaque je la monte à l'arrière de la première antenne ce qui me fait 3 couches au lieu de deux.
La partie centrale où il y a le cable, la plaque avant d'origine, et la plaque arrière récupéré sur la deuxième antenne patch.

on the second patch I takes only the front plate, the rest of the antenna where there is the cable I do not use it.
This plate I mounted at the rear of the first antenna that makes me 3 layers instead of two.
The central part where the cable, the original front plate and back plate recovered from the second patch antenna.

Interesting. It seems to work well all around you.

The ending was funny.
