Hi Group We have a Garmin GA35 GPS / WAAS antenna that needs installing for ADS-B
Garmin GDL-82. We want to install it about 2 feet aft of doors under ceiling.
Has anyone put a GPS antenna there? Any pics? What size and shape ground plane
did you use? Garmin is calling for a ground plane to extend 7.5" from the
edge of antenna all around which will make it an approx. 19" circle. Thx. Ron
P.

Ron,

Normally a GPS antenna does not need a ground plane.   It's part of the
antenna.   I'm guessing they are calling it a ground plane when it's just
shielding RF from the transponder or com radio.  I installed the EchoUAT in
my plane which uses a GPS with integral antenna.  I just mounted it on a
piece of aluminum the width of the GPS and bent in an L shape and bolted to
the top of the back bulkhead.  I'm getting a good GPS signal in my plane in
the basement.....

Hi Bill The Garmin GA 35 is an active antenna and requires a ground plane that
extends 7.5" off the edge of the antenna. Somehow 5vdc gets put in and being active
it amplifies signal. I spoke to Garmin and Steinair and both said it's necessary.
Comant antenna does not need a ground plane. Ron P.
