RE: Europa-List: Transponder Antenna

I have an aerial on a homemade groundplane of 'bid' layup/tinfoil
sandwich. It is mounted in the rear fuselage on the fuselage join line.
It works well but sometimes signal is lost when ATC ground station is
straight ahead. I suspect the engine is obstructing the signal. With
that in mind the lower the aerial position the better.
