AR RF/Microwave Instrumentation have introduced two compact, lightweight antennas for RFI/EMI field testing.
The new models, AT4418 and AT4403, available from Faraday , are designed to supply constant high intensity field necessary for testing within and beyond the confines of a shielded room.
These antennas can perform emission measurements and generate the response required for common tests in their frequency ranges.
The AT4418 model covers the 1 to 18GHz frequency range and can handle 300 watt CW input power.
It provides a minimum gain of 7dB over isotropic. The AT4403 model spans the 200MHz to 2GHz range and is intended for 1000 watts CW input power. It provides a minimum gain of 5dB isotropic.
Both antennas are mobile and mount easily on a tripod. The AT4418 and AT4403 models are built to withstand the demands of outdoor use.
