I am wanting to upgrade my antenna on my vision 2. What I mean by this is that I want to use a better antenna, but keep the same receiver board. I opened up the vision 2 and I see that there are 2 antenni. Are they in parallel? In other words, does it matter which one I use to hook my improved antenna to? I understand the camera and the wifi extender also have 2 and you can use either one, but I wanted to make sure this is the case with the 5.8ghz RX on the phantoms receiver board.
