The double ridged horn antenna model AH-118 is a broadband waveguide antenna. This antenna is linearly polarized and is designed specifically for EMC measurements for the 700 MHz up to 18 GHz frequency range. The AH-118 Horn antenna can be used for emissions and immunity testing.

The gain of this microwave antenna is at least 6.1 dBi over the entire frequency range can accept up to 300 Watts input power in continuous mode.

This double ridged horn antenna is constructed using light weight aluminum with a corrosion resistant conductive coating. The mounting base of Model AH-118 has 1/4 inch x 20 threads. This allows the horn antenna to be mounted on our AT-812 Tripod or a tripod with matching threads.

Each antenna is individually calibrated at 3 meters. The calibration data and certificate will be shipped with each antenna.

  • Frequency range: 700 MHz up to 18 GHz
  • Broadband - For sweep measurements
  • High Gain - Lower floor noise for emissions
  • Individual calibration
  • Three Year Warranty
