Model ATH18G27-1

Antenna

18GHz–26.5GHz

The Model ATH18G27-1 is a wide band, low gain, wide beamwidth, high power microwave horn antenna.

With a minimum gain of 8.8dB over isotropic, the Model ATH18G27-1 supplies the high intensity fields

necessary for RFI/EMI field testing within and beyond the confines of a shielded room. The Model ATH18G27-

1 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 ATH18G27-1 provides the 18.0-26.5GHz response required for many often

used test specifications.

The ATH18G27-1 is ideally suited for use with the AR Models 40T18G26 and other high power amplifiers in

this frequency range.
