Hi all after watching many videos on the p3s controller I took the plunge to take it apart to fit pigtail sma to the 5.8 board leaving the two 2.4 GHz antenna alone until I could find out what the left and right ones are for. the reason being I feel I may only need to upgrade one of them. my thinking behind this is one side is a transceiver for the phone link and the other for drone video and telemetry link as the phone never travels far from the controller there would be no need to fit an amp and upgraded both antennae. sadly clear precise information on this simple question seem to be alluding me I hope some boffin can help. I have noticed the 5.8 and one 2.4 ghz antennae both have black leads and one 2.4 has a grey lead my guess would be the gray one is for the phone 2.4 ghz and the two black leads for the transceivers to and from the drone. one 5.8 and one 2.4 ghz cheer hope some kind soul can help, will save me a lot of testing.
