Ok...This seems to be something that people do not understand, and just guess about it. That is why I am asking. The vision 2 has these antennas: -1 TX antenna from the controller that controls the phantom and the camera -2 RX (?) antennas located on the phantom reciever board -2 RX (?) antennas in the wifi range extender -2 TX (?) antennas insode the vision camera The reason I put a question mark on the 3 above is that their function is unclear. I assume that the both assume the same function. In other other words, the 2 antennas on the vision camera, I assume, is the TX the signal back to the wifi extender. Here are my 3 questions. I want to end the debate. 1. Do they antennas on the board serve the same function? If not, what are thy doing differently? 2. If they serve the same function, are they both used at the same time? 3. In the case of altering the antennas for upgrade, does it matter with jack you use? This depends on the above questions.
