AR RF/Microwave Instrumentation.
The ATH7G18 from AR Modular is a microwave horn antenna that operates from 7.5 to 18 GHz. It has a high gain from 10.5 to 15 dB, a VSWR of 1.2:1 and can handle up to 2800 W of power (max). A removable gain enhancer is included to insure the required field strength when conducting 3 meter testing. The antenna provides field intensities of up to 250 V/m and supplies the constant high intensity fields necessary for RFI/EMI field testing within and beyond the confines of a shielded room. 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.
