Business Editors

ORLAND PARK, Ill.--(BUSINESS WIRE)--July 10, 2000

Andrew Corporation (NASDAQ:ANDW) announced four new PD (Parabolic Dish) Series antennas and the ISM Protector, a combination bandpass filter and surge arrestor.

Durable, low-cost PD Series antennas offer excellent performance for wireless LAN, point-to-point backhaul, and other communications services operating between 1.9 - 5.8 GHz. Models are available for the PCS, ISM, MMDS, and UNII (Unlicensed National Information Infrastructure) band operating frequencies.

The new antennas have rugged spun aluminum parabolic reflectors for greater durability. Their design incorporates a new variation on the prime focus T-shaped dipole feed, a feature that has been taken from Andrew Corporation's field proven MAG GRID antenna series technology. The T-shaped dipole feed ensures superior return loss and radiation pattern performance.

The 16 inch (40.6 cm) diameter PD Series antennas weigh 3.6 lb (mass1.63 kg) and their mounts weigh 1.5 lb (mass .68 kg). The small diameter of PD Series antennas helps to minimize their shipping and handling costs. A newly configured L-shaped mast-mounting bracket is compatible with up to a 2.5-inch (6.35 cm) pipe or tower leg diameter. The mount also provides up to 60 degrees of elevation tilt adjustment.

Andrew also announced the ISM Protector, a versatile accessory made possible by a new design technology. This in-line unit provides bandpass filtering and a path to ground for lightning-induced surge pulses. The five-element design uses interdigital filter techniques for superior RF performance and manufacturing repeatability. The filter offers greater than 10 dB attenuation 50 MHz out-of-band, and greater than 35 dB attenuation 100 MHz out-of-band with a typical insertion loss of less than 0.9 dB. The unit passes industry standard surge specifications. It can be mounted onto a flat surface, such as a roof or wall, or bulkhead mounted into an equipment rack or outdoor radio unit.
