Product Details
The DRHA1600 is a compact dual-ridge horn antenna that delivers directional radiation patterns and usable gain continuously from 1.6 to 18 GHz, more than an 11:1 bandwidth in a single aperture. Its all-metal body, produced by metal additive manufacturing, and its broadband performance makes it well suited to EMC testing, antenna characterization, electronic warfare test and evaluation, and wideband signal monitoring. The antenna feeds through an SMA female connector and handles up to 25 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 1.6 to 18 GHz range.
- Compact all-metal build produced by metal additive manufacturing; to our knowledge among the smallest DRHAs covering this band.
- SMA female connector with 1/4-20 mounting; handles up to 25 W of input power.
- Each unit ships with a measured test report of VSWR and boresight gain; raw data (.txt/.s1p) and custom characterization available on request.
