Today I manufactured a mount for the upper FLARM antenna, inserted 2 x 3mm rivnuts in the upper fuselage to mount it just ahead of the vertical stabiliser. This is an interior antenna that is part of the PowerFlarm kit designed to be placed inside a glider fuselage, I'm hoping it will "see" through the fibreglass fairing, the FLARM unit will eventually be able to report if it is effective, if not I'll be able to replace it with a higher gain external antenna in the same position, hidden from view & the airflow.
