Well yes when I'm photographing a house it is sometimes almost directly overhead. I'm not out in the country where there's wide open spaces. Houses are right next to one another.
I see. So the rule of thumb is keep the flat edge of the antennae pointed toward the bird at all times. If you're flying directly above, they should be parallel to the ground. Adjust as necessary.
Yes I totally get that, what I was curious about is when doing that kind of flying could 1 antenna be flat to the ground and 1 pointed up to accommodate both angles or do they need to be the same?
Generally the same for best reception. However, if you're flying close (as in 50-100 ft), it likely doesn't matter. I've flown with the bird behind me for several hundred feet, but that's in an area w/ no interference. In your situation I'd be more afraid of losing GPS and having to deal with ATTI in close quarters than losing Tx signal (well, RTH might get interesting too).
Ok I may toy with that a bit and see if it makes a difference. It's not a big deal I can always just adjust the antennas as needed. I was just curious.
