"my avionics guy really doesn't like inside antennaes, even in a glass
plane..."

My GPS (KLN-94) was installed by one of the best avionics shops in the
Midwest, Kings Avionics at IXD.  They mounted the antenna on a phenolic
pad glassed onto the right fuse behind the tailcone bulkhead above the
hat rack.  They tested and certified it for enroute and approach IFR.
Works light a champ!
