Excuse guys if with my empirical tests or at least performing with a little radio knowledge they made it confusing. Let me first tell you what I did, starting from the assumption that I initially thought that all my problems came from transmission from drone to rc.
After doing tests with two p3s and two remote controls where a p3s went a distance of 400 meters original and my 40 meters. Reversing and relinking the situation has not changed so the main culprit in my opinion has become the drone.
At this point with great difficulty I did lend a field detector with range up to 10gz. The detector had a display with various types of indications but I just looked at that dbm.
I did two measurements off by first isolating an antenna on the drone leg with foil paper I set the detector filter (with many difficult menù) and the result was 17dbm. I released the first antenna and measured the second which gave 2.3 dbm.
Thinking that the drone would transmit then I thought the transmitter was burnt or that the second antenna was just receiving.
I do not know if I got in harmony and I do not know if the test I did was regular or just another time loss.
