Default GPS Sensor Location garmin 3210

I just bought a used 31 contender and it has a Garmin 3210 with radar dome..he GPS sensor is currently mounted on a fiberglass antenna base and it is mounted @ 12" off the base of the t-top. It folds down out of the way but I am afraid that I will eventually forget it in the up position and hit the roof of my boat shed ( boat is kept in a hoist). I don't like where it is now and I would like to move it. Does the gps sensor have to be mounted above the top of the radar dome ?? Will the radar mess up the gps signal or vise versa ?? Thanks !!!!

It can be lower than the radar beam which is typically 25 degrees top to bottom. GPS antennas don't have to be high, but they do need to see a lot of sky. They can see thru glass or plastic windows, cloth awnings, and even thinner fiberglass, and can work fairly well when tilted fifteen or twenty degrees. Radar radiates a good bit of energy, and if you sit close enough for long enough, it can screw up your eyesight and other semi-valuable bodily functions, and it will screw up electronics in the path of the beam. That includes all your receivers; cell phone, stereo, VHF, satellite, TV, GPS, etc. Consider raising the radar a few inches, or moving your GPS antenna off the top and down to the dash, or someplace else. The GPS antenna is strictly a receiver and doesn't radiate much of anything.
