Model 3164-08 Open Boundary Quad-Ridged Horn's open boundary design makes this antenna unique in both appearance and performance. It replaces former models 3164-04 and 3164-07, as this model has excellent gain and improved VSWR.

Model 3164’s open boundary design is similar to two double-ridged waveguide antennas placed orthogonally to each other. With its highest gain in the 5.8 GHz range, this antenna is ideal for WiMAX testing. Additional applications include UWB wireless testing (3 GHz - 10 GHz) and lower frequency testing (700 MHz - 3 GHz) for GSM, PCS, Wi-Fi, etc. applications. The 3164-08’s compact design makes it ideal for use as both a tripod mounted or wall mounted antenna.
