Rohde & Schwarz HF907 Horn Antenna 800 MHz – 18 GHz
Description
Rohde & Schwarz HF907 Double-Ridged Waveguide Horn Antenna 800 MHz – 18 GHz sets itself apart from conventional broadband horn antennas in that its radiation pattern contains only a single main lobe over the entire frequency range; there are no appreciable side lobes.
High gain and low VSWR permit the measurement of weak signals and the generation of high field strengths without any significant return loss. The antenna is made of aluminum to keep its weight low.
Features
- Wide frequency range
- High and flat gain
- Radiation pattern contains only one main lobe over the entire frequency range
- Compact dimensions
- High efficiency
- Input power up to 300 W
- Ideal for use in EMC laboratories
- Individual calibration in line with ANSI C63.5 and SAE ARP 958
