Model ATH2G8A
Antenna
2.5GHz–7.5GHz
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.
The ATH2G8A is ideally suited for use with the AR model 1000T2G8B and other high power amplifiers in this
frequency and power range.
The export classification for this antenna is EAR99. These commodities, technology or software are controlled for
export in accordance with the U.S. Export Administration Regulations. Diversion contrary to U.S. law is prohibited.
