The new antennas – AT 4418 and AT4403 – are designed to supply constant high intensity field 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 7dB 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 5dB isotropic.
Both antennas are extremely mobile; they mount easily on a tripod, and are built to stand up to the demands of outdoor use.
