Glider antennae for the FLARM collision alert system ... where to put them?
I have three antennae to worry about: GPS, ADS-B, and FLARM A. (FLARM B is an external antenna on the bottom of the fuselage.)
They can't be too close to each other. The blue strip of aluminum taped to the nose shows the notional canopy inner surface, so there is not much height available. Fortunately, the instrument bay top cover is fiberglass is radio transparent. If I have to drill a hole to set the tallest antenna a bit lower, that's not all that terrible.
Note, for proper antenna polarization the dipoles must be vertical.
Considering all the other antennae I have (transponder and its GPS, radio, infotainment system, SSMIS download and HAM relay), I'm starting to feel like this airplane:
