Antennae

PowerFlarm uses very small cables with high loss, don't think they
belong in the tail. Do the best you can with them near the glare
shield. Maybe you run a Flarm B cable all the way to the tail, but I'm
dubious of the benefit. Definitely wouldn't put a Flarm antenna
anywhere close to transponder output.

I'm trying to fit two FLARM antennas and a goTenna, plus GPS reception by cellphone for IGCdroid (besides the GPS reception within the FLARM) into my cockpit, and that's enough to give me a headache. Existing glider, with VHF radio antenna in the tail, but probably won't add anything to the tail. Would like to keep the goTenna far away from the FLARM antennas, since it's relatively high power (1 watt - nothing like a transponder) on a very similar frequency. Also would like to mount the FLARM antennas one forward of the pilot and one aft, to maximize the coverage by minimizing the impact of the pilot's body blocking the signals. And of course want to keep the antennas away from metal objects such as control cables and electrical wires. It's a puzzle. At least my glider is all glass, no carbon.
