I ended up buying the Gaui Vision GV-100 for its tidiness and ease. It comes as a full ready to go FPV set. I'm not really happy with the range though. It's 5.8ghz and has a fixed antenna on the Tx. My question - can I replace the Rx antenna with a polarized circular antenna or something else and will it improve my range? is there anything I can do to the fixed antenna to improve it? Does anyone have a recommendation for a good antenna to upgrade this system? Here's a picture of the setup. http://www.helidirect.com/gaui-gv100-58ghz-txrx-system-p-29001.hdx
