The Model ATH7G18 is a wide band, high gain, microwave horn antenna that provides field intensities of up to 250 V/m. With a minimum gain of 11.2dB over isotropic, the Model ATH7G18 supplies the constant high intensity fields necessary for RFI/EMI field testing within and beyond the confines of a shielded room. A removable gain enhancer is included to insure the required field strength when conducting 3 meter testing. The Model ATH7G18 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. Part of a family of microwave frequency antennas the Model ATH7G18 provides the 7.5-18GHz response required for many often used test specifications.

The ATH7G18 can also be custom calibrated to the user’s requirement for use in RF emission testing. The calibrated model is designated by adding a ‘CC’ suffix to the desired model version. Calibration details must be provided using Form 701. Contact factory for details.
