The R&S®HF907 from Rohde & Schwarz is a Double-Ridged Waveguide Horn Antenna that operates from 800 MHz to 18 GHz. It provides a gain of 14 dBi and has a VSWR of less than 3:1. This linearly polarized antenna can handle an input power of up to 300 W and has cross-polarization of less than -30 dB. Its radiation pattern contains only a single main lobe over the entire frequency range, thus standing out from conventional horn antennas. It is ANSI C63.5, CISPR 16-1-6, and SAE ARP958- rated and available in a compact aluminum enclosure that measures 305 x 226 x 280 mm with N-type (female) connectors. The antenna is ideal for EMC laboratories.
