SHF Antennas R&S®HF907 Double-Ridged Waveguide Horn Antenna
144 Rohde & Schwarz HF – VHF/UHF – SHF Antennas | Catalog 2017/2018
The linearly polarized R&S®HF907 double-ridged wave-guide horn antenna is a broadband, compact transmitting and receiving antenna for the frequency range from 800 MHz to 18 GHz.
High gain and low VSWR permit the measurement of weak signals and the generation of high field strengths without any significant return loss.
Each R&S®HF907 is calibrated individually in line with ANSI C63.5 and SAE ARP 958, making the antennas ideal for EMC measurements.
An accredited calibration of the free-space antenna factors is optionally available.
The R&S®HF907 sets itself apart from conventional broad-band horn antennas in that its radiation pattern contains only a single main lobe over the entire frequency range; there are no appreciable side lobes.
The antenna is made of aluminum to keep its weight low.
Key facts ❙ Wide frequency range ❙ High and constant gain ❙ Low VSWR ❙ Radiation pattern contains only one main lobe over the entire frequency range
❙ Input power up to 300 W CW/500 W PEP ❙ Ideal for use in EMC laboratories ❙ Compact size ❙ Each antenna is calibrated individually in line with ANSI C63.5 and SAE ARP 958
