GPS WAAS GA 35 antenna

[raymondscott0321]

Recommendations for GPS WAAS GA 35 antenna installation point on a SuperD for the Garmin GDL 82? Would like to minimize the cost of opening the fabric if avoidable.

Mine is right next to the baggage door. Required removal of the interior above the baggage compartment and the lower trim along the left side to run the cable.

Some options - I bought a Comant CI2580-200 for a combine VHF and GPS antenna to save on installation costs and to reduce the number of antennas I need

A used CI2480 might be acceptable for a GDL82 and used units are often more available.

And if you already have a GNS/GTN, maybe an antenna splitter would be an option?

My Aspen RSM was mounted on top of the tailcone in my M20J. When I replaced the Aspen with a G3X, I had a G3X external GPS antenna mounted in the same location. The location was near the front of the dorsal fin, but it is plastic and doesn't block the signal.

@Aerodon I’m in the process of switching over to the vhf/gps antenna. Where did you put it? Im weighing my options since it won’t work in the original location.

@shiver.  I am going to replace the VHF antenna just forward of the dorsal fin.  There is a proper double underneath (look for the triangular rivet pattern).  My current thinking is to plug the old holes with rivers and a 'button' and start again alongside.  No easy way of using the old holes.

I am installing a traffic antenna just forward of the other VHF antenna using the Moonye instructions for a doubler braced against the tubular structure.  Then moving that VHF to the belly.
