Hey guys!
I'm newbie. Cheers.
I am working on boosting the effective RF range for P4 pro v1.0 and v2.0. (Guess the method should be the same despite Lighbridge for P4P 1.0 while Ocusync for P4P 2.0). Here are my questions concerning the range extending solution and hope you guys can help me out.
1. Antenna Function
1) There are four antennas on the RC and four anttenas on the aircraft (correct me if I was wrong)----confirmed
2) The left antenna on the RC is for transmitting control signal to the drone only(Tx) while the right one is for receiving FPV streaming from the drone only(Rx)/Both the two antennas can work as a transmitter or receiver simultaneously----to be confirmed

3) Two front legs (#1 & 2) are for FPV transmitting while two back legs (#3 & 4) are for control signal receiving----to be confirmed
2. Modification Solution
My trial is to add both booster(power amplifier) and antenna (more gain) to the RC/drone (or both)
1) Here is my current setup:
I removed the stock antennas from the RC and mounted two SMA jacks. I used one 2.4/5.8 auto-switch and bi-directional AMP from Sunhans on the left jack. I wired both SMA jack to two panel antenna and drive them with a tracking gimbal. Any problem?
2) or I should do the following:
3) I did see some 3rd party solutions that use 2 AMPs on the RC. Does it really make sense?
Also, AMPs have one input port(to radio) and one output port(to antenna), I found the setup in the picture below shows that the 2 RF cables from the RC always go to the input port of the AMP first and then to the atenna. Does it confirms both antennas on the RC have transmitting functions besides possible receiving funtions? a bit confused.......
3. Modification Solution in the future
I am designing further. See the picture below. Any suggestions? For example: Long trace of RF cable brings with more signal loss and thus may even exhibit poorer performance than stock antennas?
Thanks for your interest guys!!!!!!
