The Model ATH2G10 is a wide band, high gain, high power microwave horn antenna. With a minimum gain of 12dB over isotropic, the Model ATH2G10 supplies the high intensity fields necessary for RFI/EMI field testing within and beyond the confines of a shielded room. The Model ATH2G10 is extremely compact and light weight for ready mobility, yet is built tough enough for the extra demands of outdoor use and can be easily mounted utilizing the rear flange. Part of a family of microwave frequency antennas, the Model ATH2G10 provides the 2–10 GHz response required for many often used test specifications. The ATH2G10 is ideally suited for use with the AR Models 1S4G11, 5S4G11, 10S4G11A, 20S4G11A, 300T2G8M3 and other high power amplifiers in this frequency and power range.
