A suite of three high-gain, high-power microwave horn antennas from AR RF Microwave are intended for use in DO 160 HIRF (high intensity radiated frequency) testing. These antennas provide even more options for varying test conditions. The AT4444 provides 2 to 4 GHz/ 1000 watts CW / 17-kw pulse input power while the AT4446 provides 4 to 6 GH / 800 watts CW /15-kW pulse power. The third member of the suite, the AT4448 provides 6 to GHz / 700 watts CW / (7.6 to 8 GHz) / 10-kW pulse input power. All of these high-gain, high-power microwave horn antennas provide a minimum of 18 dB over isotropic. They supply high intensity fields for DO 160 HIRF testing. They are compact, lightweight, and sturdy for easy outdoor use. All three mount easily on a tripod or to a mounting plate and can be used with AR’s power-pulsed wave tube amplifiers.
