Product Details
The DRHA750 is a broadband dual-ridge horn antenna that delivers consistent directional radiation patterns and usable gain continuously from 750 MHz to 8 GHz, a 10.7:1 bandwidth. Its rugged aluminum body and stable beamwidth make it well suited to EMC testing, antenna characterization, electronic warfare test and evaluation, and wideband signal monitoring. The antenna feeds through an N-type female connector and handles up to 50 W of input power.
- Suited to EMC radiated emissions and immunity testing, antenna characterization, electronic warfare test and evaluation, and wideband signal monitoring.
- Dual-ridge design maintains a directional pattern and usable gain across the full 750 MHz to 8 GHz range.
- Rugged aluminum construction with an N-type female connector and 1/4-20 mounting holes.
- Handles up to 50 W of input power.
- Each unit ships with a measured test report of VSWR and boresight gain; raw data (.txt/.csv) and custom characterization available on request.
