DO NOT install the MR-350 in close proximity of other RF antennas as the power output from radios can effect GPS reception.  Exact mounting distances from other antennas can vary, so it is high recommended that you temporarily attached the MR-350 in the desired mounting area (wire tie, tape, etc) and fully test the location while using your other radio equipment to verify that there is no interference before drilling your permanent mounting hole.
