Marine Antenna Separation
Marine Antenna Separation
(OP)
Does anyone know of a good resource to find recommendations for the physical separation of marine antennae and associated equipment such as GPS, VHF, Inmarsat C, Fleet 77, HF, Marine Radar.
I am also looking for information on materials and methods that admit these frequencies while blocking others and lowering the radar cross section.

RE: Marine Antenna Separation
Unless you are involved in a major military project you're probably better off with a few rules of thumb (and perhaps some extra bandpass filters) than the cost and effort of developping an accurate RF model of the ship.
The most common naval technique of reducing radar cross section is to limit/eliminate corner reflectors within the ship's structure. Good examples are the Canadian CPF and French Lafayette designs. A great example is the Swedish Visby Class corvette. The Visby is also an example of enclosing all antennas within a single radome to reduce radar cross section. Another passive technique is applying RAM to high signature areas.
