The Model 3164-06 Open Boundary Quad-ridged Horn Antenna's open boundary design is similar to two double-ridged waveguide antennas placed orthogonally to each other, and its surprisingly compact size offers improved pattern and gain when compared with enclosed quad-ridged horns of similar dimensions.

The 3164-06 has exceptional bandwidth, with operating frequency band for optimum performance from 300 MHz to 6 GHz. Two orthogonally placed input feeds allow this antenna to generate both linear and circular polarized measurements across the entire frequency band, without manual polarization.
