Antennas
Directional Ceiling-mount Array
The model S1857MD directional PCS-band antenna for ceiling-mount applications exhibits 7 dBi of gain in the 1850 to 1990 MHz frequency band. The antenna’s housing is vacuum-formed from UV stabile thermoplastic and best suited for use with microcells, picocells and RF distribution systems where directional coverage is desirable from a mounting location overhead. (Standard models are available in white with a textured finish.) The antenna measures 3.75" x 7.25" x 2.00" and weighs 3.2 oz.

LMDS Hub Antennas
The SectorShape™ antennas for local multipoint distribution system (LMDS) hubs are designed using a highly automated process that takes advantage of advanced electromagnetic analysis and artificial intelligence and provide good conformance to pattern requirements in point-to-multipoint systems. Horizontal and vertical polarization are available as well as 45° and 90° azimuth coverage. Covering the 24.5 to 32 GHz range in three frequency bands, the antennas offer greater than 40 dB cross-polar rejection at all angles without the need for a polarizer. Gains for the 45° azimuth are typically 22.5 to 23.5 dBi while the 90° azimuth demonstrates gains of 20 to 21 dBi. The antennas are weather sealed and UV hardened, and optional heated radomes ensure continued operation in ice and snow conditions.
