Gps antenna spacing. Typically, the best location is centerline as high and far forward as possible, just aft the windscreen. Vertical separation between antennas always provides better isolation than horizontal separation. Select an antenna mount suited for the specific antenna and vessel type. If vertical Spacing to Other Antennas & Equipment If the antenna is to be installed on an aircraft with a SATCOM (INMARSAT, 1625 MHz) antenna, 4 feet minimum spacing is recommended. 2 feet between Radar & VHF antennas. Avoid mounting antennas or routing coaxial cable near other communications equipment, which could generate frequencies harmonic to the GPS 1575 GHz frequency. By employing advanced Knowledge Base How much antenna separation do I need on my boat? Many marine vessels have multiple antennas for VHF, radar, GPS, and other systems. ” Jun 3, 2016 ยท If multiple frequency antennas are near each other, then use the spacing distance of the lower frequency antenna, or even better, try to satisfy the rule for both frequencies. Spacing less than 9 inches center-to-center results in unacceptable antenna pattern degradation. I recall mixed comment about spacing two, for example 26C and 35A in close proximity. i05ujh it4j lzfunf q7g mur ax jwh bq v0x cchaq9
