GPS antenna location

Rob wrote in news:a999739f-3fe0-4e5a-b019- : 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 Bob 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. |
