Richard-
I am using an AAE antenna and it works fine. It is a folded dipole mounted
vertically.
It is mounted on a piece of balsa wood FLOXed to the inside of the fuselage
near the bulkhead containing the elevator weights. RG-400 is a good idea
too. With a vertical dipole you do not need a counterpoise. The AAE antenna has
a BNC connector already fitted, so you just FLOX it in and you are good to
go. I think the Bob Archer antenna is similar.

the coax from RG58 to RG400. My current ground plane is an aluminium plate
about 8in diameter, half moon shape with a lip which is fixed behind the baggage
