Amplifier Research ATH18G40 Waveguide Horn Antenna 18 GHz – 40 GHz

Description

Amplifier Research ATH18G40 is a wide band, high gain, and high power microwave horn antenna. With a minimum gain of 15.2dB over isotropic, the Model ATH18G40 supplies the high intensity fields necessary for RFI/EMI field testing within and beyond the confines of a shielded room.

The Model ATH18G40 is extremely compact and light weight for ready mobility, yet is built tough enough for the extra demands of outdoor use and easily mounts on a rigid waveguide by the waveguide flange. Part of a family of microwave frequency antennas, the Model ATH18G40 provides the 18-40GHz response required for many often used test specifications.

Features

  • Wide beamwidth, high gain, microwave horn
  • Compact and lightweight
  • Supplies constant high intensity fields necessary for RFI/EMI field testing
  • Tough enough for outdoor use
  • Compliant to many military and commercial emissions standards
