When mounting a Stratux receiver into the back of a plane, the antennas need to be placed at the window. To fix everything in place, I designed this holder which carries antennas for ADS-B and FLARM (see my Stratux DIY Dipole Antenna) and a UBLOX M8030 Dual GNSS USB receiver as available through the standard sources.
