Linear Polarized Feeds

MI-233 Family of Single Polarized Feeds

Description

Model: ANT-LPF

The ANT-LPF Family of Compact Range Feeds offer a complete line of linearly polarized high performance feeds covering frequencies from 0.75 to 40 GHz. Each feed is designed to ensure maximum performance when used in NSI-MI Technologies' compact range measurement system.

Each feed horn generates the broad beamwidth (30 degree 1 dB beamwidth and 60 degree 3 dB beamwidth) radiation pattern required to optimize the performance of most compact range reflectors. This optimized radiation pattern is maintained over the full waveguide frequency bandwidth. Thus, maximizing the Compact Range System performance. Like other NSI-MI Technologies feeds and antennas, our Linear Polarized feeds are designed and manufactured to provide many years of useful life in the test range.
