Product Details
The EHA-WR62 is a Ku-band exponentially-tapered horn antenna covering 12.4 to 18 GHz with symmetric E- and H-plane radiation patterns and a nominal gain of 12 to 15 dBi. The smooth exponential flare suppresses sidelobes and produces a clean, rotationally symmetric main beam, making it well suited to antenna gain reference and measurement, EMC testing, and use as a reflector or lens feed. It presents a standard WR-62 (UG-1665/U) waveguide flange; an optional AntenX SMA-WR62 coax-to-waveguide adapter adds an SMA interface for direct cabling.
- Exponential taper produces symmetric E- and H-plane patterns (typ ~38° HPBW) with low sidelobes across the full 12.4 to 18 GHz band.
- Suited to antenna gain reference and measurement, EMC testing, reflector and lens feeds, and over-the-air test setups.
- Standard WR-62 (UG-1665/U) waveguide flange; pair with the AntenX SMA-WR62 coax-to-waveguide adapter for an SMA (coaxial) interface.
- Compact, lightweight all-metal aluminum construction.
- Available as the bare horn or bundled with the SMA-WR62 adapter; choose the model when ordering.
