Kevin,

I have found that the antennas interfer with eachother and you may not
get GPS locks on one or both.

I once mounted a CAI 302 Active antenna and a Colibri active antenna
next to eachother. The Colibri would not lock. I move the antennas
about 2' apart and all worked OK.

Hi Folks,

Does anyone out there know if there are any adverse
effects of mounting two or more GPS antennae in close
proximity?

I'd like to fit two (maybe 3 !!! ) antennae (Colibri
/ EW type 'Radomes') on the instrument panel coaming
of my Discus. Is this likely to cause any problems
in acquiring or tracking the GPS position?

Thanks

Kevin
