The Model ATH4G8 is a wide band, high gain, microwave horn antenna that provides a minimum gain of 11.5dB over isotropic. The Model ATH4G8 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 ATH4G8 is compact and light weight for ready mobility, yet is built tough enough for the extra demands of outdoor use and easily mounts on a tripod. Part of a family of microwave frequency antennas the Model ATH4G8 provides the 4-8GHz response required for many often-used test specifications.
