vulcan2go, there are soooo many antenna manufactures and designs out there, if you could, send me/post a link to where you got your antennas. I also have one or two of the Immersion TX's, and two of the "Black Mamba" (2 watt ????) TX's, and about 20 different antennas. Flipped my F450 onto it's top yesterday, flying in a new place, (where'd that tree come from?), and bent the chit out of my antenna. (clover leaf), and to be honest, I have bought so many, I don't know where I got this one, but it seems to work OK. I also have an Immersion power meter, so I can measure the performance of different setups. There's a whole lot to this stuff, ain't there?
