Hi guys, I'm new here. I've had my Vision for about a month and have had no issues to date…and am loving it . I purchased a RE700 to extend my FPV (worked like a charm!) and I performed the transmitter mod so that I could use an aftermarket antenna to extend my range. I installed a U.FL to RP-SMA pigtail and am using a TP-Link 5dBi antenna like this one (http://www.amazon.com/gp/product/B004PF ... UTF8&psc=1). The problem is that I think I may have shorted my amp in the radio because I'm only getting 1800ft transmission and then I lose communication when I read that I should be getting much much more. (I fly out in the open countryside…no wifi noise at all) Long story short, before I go out and buy a new radio, is there a way to check my antenna output with a multimeter? Or should I buy a FPVLR transmitter antenna and try that? Thanks in advance guys!
