Wide Band Active Horn Antenna
The AHA-118 is a broadband, linearly polarized Double-Ridge Horn Antenna with a built-in 40 dB gain, low-noise preamplifier.
- The AHA-118 Active Horn Antenna covers 700 MHz to 18 GHz for EMI and EMC testing.
- Handles up to 300 Watts continuous input power; ideal for high-power EMC immunity testing across broad RF bands.
- It features a built-in 40 dB low-noise preamplifier for high sensitivity.
- Supports both transmit and receive functions for versatile RF testing.
- Compliant with major standards like FCC, CISPR, EN, ETSI, MIL-STD-461, and RTCA DO-160 for global regulatory acceptance.
- Includes NIST-traceable calibration per ANSI C63.5 or SAE ARP958.
- Built with rugged, corrosion-resistant aluminum for lab and outdoor use.
- Comes with a standard 1/4" x 20 mount and right-angle bracket for easy setup.
