I have been getting conflicting advice about relative position in
regard to my radar dome. Both will be mounted on my mast about 12 to
24 inches apart. I have a choice of having the GPS right below the
bottom of the dome or I could put an extension and have it extend a
few inches above the dome. Any advice?
Thanks

Wrong attitude. The GPS antenna has no need for ALTITUDE. Aboard
Lionheart, I got tired of them bumping into both the Raystar little dome
and the Garmin active antenna, so I mounted them INSIDE the overhead
cabinet in the galley
Belowdecks is the way to go in a fiberglass boat.
My friend held the antenna alternately in the clear abovedecks, and
belowdecks hard up against the coachroof in various spots. I watched the
signal strength indicator on the chartplotter as she moved the antenna
between the abovedecks and belowdecks positions. In many spots
belowdecks there was no difference in signal strength from the
satellites with the antenna abovedecks or belowdecks.
My GPS antenna is now mounted in a good spot belowdecks, out of the
weather, away from running rigging and flying feet.
