View Full Version : Again with FLARM antenna questions.

As I plan my powerflarm brick/butterfly display installation I'm left with questions about antenna placement. I have read all the threads here on RAS and searched around other sites without results, but would appreciate a link to any source I've missed. My questions concern some missing clearances and a lack of information about installing in a XPDR glider.

Thanks for any advice, I'd like to get this close the first time,

Brian




Questions:

1. Minimum distance from FLARM RF antennas and the ADS-B/XPDR antenna?

2. Minimum distance from FLARM RF antennas and an existing (Microair 200 watt) XPDR antenna?

3. Minimum distance from ADS-B/XPDR antenna and an existing XPDR?

4. Minimum distance from Compass to GPS antenna (4"?)




-----------------------------------------------------------
From the Powerflarm manual:
Min. distance between RF antenna on FLARM A and compass: 4"

Min. distance between RF antenna on FLARM A and FLARM B port: 1ft (0.3 m)

Min. distance between RF antenna on FLARM A port and GPS antenna: 1ft (0.3 m)

Min. distance between RF antenna on FLARM B port and GPS antenna: 4in (0.1 m)

Min. distance between ADS-B / XPDR antenna and GPS antenna: 4in (0.1 m)

Do not mount antennas on conductive material (e.g. any type of metal, carbon fibre)!
