Henri Squier Posted January 6, 2016 Share Posted January 6, 2016 Hi everyone, Do you have some suggestion ? A ?, B ? C, D or E ? In other terms do I have to worry a "masking shield " from the LIPO / motor ?... or from the board cam ?... that will make me loose the video signal when I'm "behind" ? Could balsa wing also be a "shield" ? Or is this not a problem and it works whatever the position of the antenna ? Thanks for your wise thoughts, henri.

flight1 Posted January 6, 2016 Share Posted January 6, 2016 First off what Rx are you using( 2.4Ghz) and how big plane? Quote Link to comment Share on other sites More sharing options...
Geoff S Posted January 6, 2016 Share Posted January 6, 2016 It seems to me options C Dand E would be ruled out because of their vulnerability if you have no undercarriage and they would be just as screened as the options A or B if you did have one. Quite honestly, I think your over thinking it. There are always going to be problems with less than optimal transmission in some orientations where ever you fit the antennae. I think I'd opt for position B as the least worst Geoff Quote Link to comment Share on other sites More sharing options...
GONZO Posted January 6, 2016 Share Posted January 6, 2016 With FPV it is usual, on a flying wing(delta) to place the RC Rx antenna out on one wing and the video Tx antenna out on the other wing giving maximum separation and reduced interaction. On a conventional plane the video Tx antenna should be placed at the rear of the plane up on the fin. Balsa will have no effect on the video signal. Are you on any dedicated FPV forums? If not come back and I or others will provide some links. This sort of info and more is available in the starters/beginners threads on these forums.

Henri Squier Posted January 7, 2016 Author Share Posted January 7, 2016 Hi, Thanks for answers. Sorry for lack of information : the plane is balsa trad build, 46 inches, will have undercarriage, radio Tx is 2.4 Ghz and video signal on 5.4 Ghz. ... and for GONZO I'll be happy with your offer, i'm not in any FPV forum and I'll be pleased if you can give me some good links. henri Quote Link to comment Share on other sites More sharing options...
GONZO Posted January 8, 2016 Share Posted January 8, 2016 UK based forum **LINK** (Be sure to read and understand the legalities of FPV in the UK if this is where you are) US dedicated forum **LINK** Part of US forum **LINK** You'll find others if you do a Google search. But, I think these will give you plenty to read for now. HTH Edited By GONZO on 08/01/2016 08:42:52 Quote Link to comment Share on other sites More sharing options...
Henri Squier Posted January 23, 2016 Author Share Posted January 23, 2016 Thanks a lot Gonzo (sorry for delay), henri. Quote Link to comment Share on other sites More sharing options...
Flynn Posted February 16, 2016 Share Posted February 16, 2016 Henri - I use 5.8 Ghz and site the video TX at the rear of the cockpit for fixed wing, for convenience. This has least impact on the CG. On quads, especially 250 size, it tends to be quite close to the flight controller, GPS, 2.4ghz Rx and the battery, ie a couple of inches. I have found no problems at all with the quality of the video signal. There will be masking from the battery and certain other items on the model, and the frame itself on carbon fibre quads, but the model will be changing orientation so quickly that any masking will be momentary and not an issue for flying. The quality of components used will have a larger impact on signal and image quality. Quote Link to comment Share on other sites More sharing options...
