The ground plane for a transponder antenna only needs to be about the size of a 4" circle.  A  0.020 piece of aluminum works well...

Hello all,

Behind the rudder pedal the antenna for the transponder can be ID'd by the brown Rg cable.

ATC sometimes loses my squawk and I am thinking I need to add a ground plane.  Question for the group is if I can paint conductive paint around the antenna and under neath the hydraulic lines as much as possible.  Will the Jeffco tank sealer interfere with effecitveness?  Do I need to remove the antenna or can the hub be painted to provide continuity?

Any suggestions welcome.

Thanks,
John
