A new diagonal polarized horn antenna specifically designed for wireless test applications was announced by ETS-Lindgren. The antenna has two orthogonally placed feeds for simultaneous measurements in north horizontal and vertical polarizations. Polarization can be either linear or circular. Cross polarization isolation is better than 25 dB. The antenna covers the frequency range of 400 MHz to 6 GHz, which includes most wireless service frequencies. Intended as a receive antenna, this model may also be used as a radiator with a 200 W maximum continuous power handling capability. The Model 3164-03 Diagonal Dual Polarized Horn includes a mounting flange and calibration factors.
