HF_ATL 0 Posted March 23, 2010 Report Share Posted March 23, 2010 (edited) In my first fpv flight I got some interference (black lines) My video is: Setup: 1280mhz, 700mw output power tx with 1/4 lambda monopole homemade and stock rx antenna. r/c 35mhz ff7, rp8d1 rx Any idea of what may be causing this? Thanks Edited March 23, 2010 by HF_ATL Quote Link to post Share on other sites
Doofer 0 Posted March 26, 2010 Report Share Posted March 26, 2010 Seems a bit worse when you're close in - not so much interference on the picture, rather intermittant loss of frames. It looks like my original setup. I'd put my $$ on multipath interference (the direct signal is interfered with by a reflection 180 degrees (half a wavelength) out of phase), which unfortunately isn't made better by more power. You could buy or borrow a diversity setup and try two receiver aerials separated in space; I found this sort of problem largely eliminated by my Oracle diversity. You could also try lowering the video transmit power, as that might help a bit. Quote Link to post Share on other sites
