I installed my ground plane inside my carbon fuselage. Used a blade antenna

just aft of the gear doors and offset slightly to the right due to the

thickness of the fuselage at the glue joint. Passed transponder test at

avionics shop and is clearly visible to ATC.

Got a question for all you radioheads out there. I am installing a Becker

Xnder and I notice my other glider has a 8"x8" or so grounding plane

attached (glue?) on the inside where the antenna is mounted. Question??? I

need ground plane information such as size, thickness, installation tips,

do's and don't, ideas. The Becker is a 250 watts version and I will be

using a small 2.5" wire rod type antenna. Thank you all, R



Thickness does not matter. I usually use a piece of .016 aluminum.

Installation manual should define sise, but about 5 inches in diameter is

what I recall.

On glass ship it can go inside. On carbon ship I put on outside behind the

gear with 2 sided tape.

Or use a di-pole antenna that doesn't need a ground plane. I mounted mine all inside the fuselage just forward of the rudder.
