Model AH-640 is a broadband linearly polarized standard gain horn antenna designed specifically for Electromagnetic Interference testing. This antenna can be used for receive as well as transmit applications for the frequency range of 26.5 GHz to 40 GHz.

This antenna has a high gain with at least 23 dBi over the entire frequency range. This antenna can accept up to 5 Watts of input power at its terminals in continuous mode in the applicable frequency range for generating electromagnetic fields.

The AH-640 Horn antenna 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 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 antenna gain.

  • Frequency range: 26.5 to 40 GHz
  • High Gain - Lower Floor Noise for Emissions
  • Individual calibration
  • Three Year Warranty
