NSI-MI offers a linearly-polarized, high-performance feed covering frequencies from 75 to 110 GHz. This feed horn generates the broad beamwidth (30° 1 dB beamwidth and 60° 3 dB beamwidth) radiation pattern required to optimize the performance of most compact range reflectors. Optimized radiation pattern is maintained over the full waveguide frequency bandwidth; thus maximizing the compact range system performance. Like all other NSI-MI Technologies' antennas, ANT-LPF feeds are designed and manufactured to provide many years of useful life in the test range.

Storage case included.
