i'm using a fatshark vtx and fatshark attitudes goggle and when i get about 50' out, even with no obstructions around, the signal starts to deteriorate pdq. at first, i thought it was battery noise, so i bought ibcrazy's filter and that had no impact whatsoever. so then i thought i'd try a separate battery for the camera and vtx. made a little difference but not much. so i'm just about out of ideas. anyone have any thoughts? i'm using fatshark CP antennas, which ought to be good enough, I think, buy maybe i should upgrade? all thoughts appreciated!
