RADAR CROSS SECTION INSTRUMENTATION ANTENNAS

These pages list a series of custom antennas designed for demanding Radar Cross Section measurement systems. Antennas are available for ground, helicopter and aerostat environments. All Seavey Engineering RCS instrumentation antennas are designed to handle substantial peak RF power levels over wide frequency bandwidths with minimum ringing. In diameters up to 60 inches, all reflectors are fabricated from accurite, Lightweight and rigid epoxy-graphite honeycomb material.
