Hello all,

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

ATC sometimes l= oses my squawk and I am thinking I need to add a ground plane.  Questio= n for the group is if I can paint conductive paint around the antenna and un= der neath the hydraulic lines as much as possible.  Will the Jeffco tan= k sealer interfere with effecitveness?  Do I need to remove the antenna= or can the hub be painted to provide continuity?

A= ny suggestions welcome.

Thanks,
John
