ANTENNAS

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.

LMDS Subscriber and Base Station Antennas
These local point-to-multipoint distribution system (LMDS) subscriber antennas and base station horns operate over a frequency range of 24 to 38 GHz for indoor or outdoor applications. Single or dual polarization is available as well as a coax or waveguide interface. Gain is 35 to 43 dBi, and operating temperature range is -40° to +80°C. Size: 10" to 21" in diameter; 4" to 8" in depth.

Wireless Antenna
The SX series portable antennas operate over the frequency bandwidth of 150 to 161 MHz and can be up to 20 percent shorter at the same frequency as industry-standard injection-molded antennas. The antenna's patented capless sheath construction increases its durability. SWR is < 1.5 at resonant frequency. The SX series is offered with a standard MX connector and an assortment of SMA female connectors. It is available in UHF and VHF. Length: 5.5 inches (140 mm).
