250 V/m Field Antenna
The model AT4002A microwave horn antenna is capable of generating fields of up to 250 V/m with a gain of 11 dB (max) over isotropic. It accepts 250 W of input power from 0.8 to 5 GHz and supplies the high intensity fields necessary for electromagnetic/RF interference field testing in shielded rooms. Specifically designed septums are installed to focus beamwidth and ensure field intensity at three meters. The unit mounts easily on a tripod or back plate. Size: 46.3 x 46.3 x 69.2 cm. Weight: 6 kg.

Antenna Mount
This point-to-point antenna mount, the Quick Align Mount (QAM), simplifies the installation and alignment of an antenna. The mount adapts to mast pipes ranging in size from 1.9 to 4.5 inches. The QAM requires only a wrench and screwdriver for on-site installation of antennas. The new mount is currently being supplied with the company's new antenna models SSP2-23A and SSP2-52B. It is also available on select directional flat-panel antennas.
