The Model ATH2G8A is a wide band, high gain, high power microwave horn antenna that provides field intensities of up to 500 V/m. With a typical gain of 14dB over isotropic, the Model ATH2G8A supplies the high intensity fields necessary for RFI/EMI field testing within and beyond the confines of a shielded room. The Model ATH2G8A is compact and light weight for ready mobility, yet is built tough enough for the extra demands of outdoor use. Part of a family of microwave frequency antennas the Model ATH2G8A provides the 2.5-7.5GHz response required for many often used test specifications.
