In the RV8, the GPS antenna locations has been a battle of compromises. I'm told that under the cowl works well, despite Garmin's objections to putting them there. I was told by my avionics guru (S) that I should separate the G3X antenna from the GTN650's by 6+ inches, so here is what I came up with.
I have two questions for those a bit more experienced than I am with these things. First, under the cowl is fine right? Second, these antennas have a forward arrow on the drawings and to save space, I blew that suggestion off and turned them sideways. Can someone explain how a GPS antenna would need one end pointing forward? Of course I was completely certain it wouldn't matter...until it was finished...now I'm questioning my brilliance. Any thoughts?
