Default radar/gps antenna placement

i was told that your gps antenna had to be positioned above the location of your radar antenna. Is this true?

Look in your GPS manual. The usual requirement is three feet of seperation and out of the beam. So that means it could also be lower than the radar, especially if you have a "Scanstrut" or similar radar mount that elevates it.

My GPS antenna was originally installed in the same plane as the radar beam. Whenever I would turn on the radar I would lose GPS signal. Since I moved the GPS antenna up, I haven't had that problem...

3" above or below is good enough.

Yep, just above or below the radar beam. Remember, the "radar beam" is the top half of your radome.
