A. Filters help reduce interference from other transmitters in the area. You own or a nearby Marine VHF Radio for instance. Naval antennas have special filters to reduce this potential for interference. There are also filters to reduce interference from FM stations and Two-way radio stations and Paging Transmitters. A technician adjusts each filter manually while using a Network analyzer to view the filters passband to insure razor sharp interference rejection. Our smallest antenna has 11 separate filter adjustments.
