AS-48461 Series Dual-Polarized Quad-Ridged Horn Antenna

In addition to excellent interport amplitude and phase match, the horn exhibits exceptional isolation between the two coaxial terminals.

Although the AS-48461 horn antenna has been widely applied as an individual test source and as array elements in electronic environment simulators, it is also ideally adaptive for wideband surveillance and direction-finding systems. Optional configurations that are available include circular polarization, polarization switching, and higher power capability (see available configurations below).
