I'm posting this here because I figure like me, many of you are followers of David's tricopter setup. I started multirotors coming from a fixed-wing background, where we're always told to tilt the transmitter antenna (in a 2G4 system) so it's parallel with the ground and pointing sideways, so it doesn't point at the plane.
Well I use a Hitec 6ch Rx, with a single BODA (i.e. whip) antenna on a mast pointing straight up to the sky on my tricopter. Because it's a multirotor, I can be pretty certain that Rx antenna will always be pointing up - I'm not going to be doing any flips or anything like that.
Should I be re-thinking how I position my Tx antenna?
The Rx antenna being vertical would have the best gain for vertically polarized waves, but of my Tx antenna is horizontal, am I losing a bunch of range needlessly? I'm thinking I should be poining my Tx antenna up to the sky so it's parallel with the Rx antenna.
I never had an issue with the Hitec setup because I've laywas been flying LoS, but I picked up some Fatsharks yesterday to get into FPV. I'm not planning a UHF system for now, but I'd like to get as much as possible out of my Hitec.
Your thoughts are appreciated.
