Model AH-840 is a broadband linearly polarized double ridged horn antenna designed specifically for Electromagnetic Interference testing. This antenna can be used for receiving as well as transmitting applications for the frequency range of 18 GHz to 40 GHz.

This antenna has a high gain with at least 20 dBi over the entire frequency range. This antenna can accept up to 5 Watts of input power at its terminals in continuous mode for generating electromagnetic fields for immunity testing.

The AH-840 double-ridged horn has a K type connector which can mate with SMA type connectors. The antenna is constructed using lightweight aluminum with a corrosion resistant finish. The oval rear plate has a 1/4" x 20 threaded hole for mounting it to the Com-Power AT-110 tripod.

The antenna is individually calibrated at 1 meter and data and certificate of calibration will be shipped with the antenna. The data will include the antenna factor and gain of the antenna.

  • Frequency range: 18 GHz to 40 GHz
  • High Gain
  • Individual calibration
  • Three Year Warranty
