The new antennas - AT4418 and AT4403 - are designed to supply constant high-intensity fields necessary for testing within and beyond the confines of a shielded room.
They can also be used to perform emissions measurements and to generate the response required for many common tests in their frequency ranges.
Model AT4418 antennas cover the 1 - 18 GHz frequency range and can handle 300 watt CW input power.
It provides a minimum gain of seven dB over isotropic.
Model AT4403 antennas span the 200 MHz - 2 GHz range and is intended for 1000 watts CW input power.
It provides a minimum gain of five dB isotropic.
Both antennas are extremely mobile; they mount easily on a tripod, and are built to stand up to the demands of outdoor use.
