I would think an antenna lying on its side would not be as effective as one protruding from the fuselage, if for no other reason the polarity will be horizontal vice vertical and that can cause significant signal loss.  Also, the radiation pattern will be greater outward on the aircraft side, since the aircraft is in fact the ground plane.

I can remember reading, but don’t know where, that you ground it through the nutplate.  I.e. you rivet the antenna between the nutplates and the wingtip.

Randy,I have a flying Rv-10.Panel was built by aerocraft.I am trying to mount Bob archer ant and am curious how you grounded it given the fact the wingtips slide inside the skin?Anyone else familiar and have suggestions?

If you look closely, you’ll see he doesn’t need an antenna.  All the pilot has to do is stick his head out the door and yell for a taxi clearance.

Nav, MB antennas = horizontally  polarized

 Com, transponder, = vertically  polarized

 Sat based antennas = circularly polarized (no ground  plane)

 Subspace antennas = strange polarization (quantum ground  plane)

Rick, I have 2 com antennas. One whip and one in the wing tip.  The wing tip is about 70% as good as the whip.  Plenty good enough if you don’t want extra antenna hanging out.  Personal choice.  Randy
