Product Details
The DRHA1800 is a compact dual-ridge horn antenna that delivers directional radiation patterns and usable gain continuously from 1.8 to 11 GHz. Its lightweight all-metal body, produced by metal additive manufacturing, makes it well suited to EMC testing, antenna characterization, electronic warfare test and evaluation, and wideband signal monitoring where size and weight matter. The antenna feeds through an SMA female connector and handles up to 10 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 1.8 to 11 GHz range.
- Compact, lightweight all-metal build produced by metal additive manufacturing (3D printing).
- SMA female connector with 1/4-20 mounting holes; handles up to 10 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.
