NEWMARKET, England - Feb. 26, 2014 - PRLog -- Cobham Antenna Systems, Microwave Antennas (Cobham), a leading antenna producer, has developed a dual-polar UHF sector antenna for use in the ‘White Space’ frequency bands. This is the first product in a range of similar dual-polar base station antennas, which will be available from Cobham soon, in 2GHz, 3GHz and 5GHz bands.

Cobham’s wideband SA11-90-0.6VH/2178 antenna provides both vertical and horizontal polarisations. In conjunction with radios, having two-port diversity, it can provide non-line-of-sight (NLOS) connectivity and reliable communications in challenging environmental conditions.

The SA11-90-0.6VH/2178 antenna covers the entire frequency range 470-700MHz, meaning that it can be used in situations where a number of channels are spaced widely apart. With fewer antennas needed, operators and installers will incur lower inventory and installation costs.

The ‘White Space’ frequency band has been opened following the discontinuation of analogue television transmissions in some countries. The available frequencies have been allocated for both licensed and unlicensed uses producing exciting opportunities in long distance yyqcv communication.

The UHF band is recognised for the ability to provide communications over large distances; across remote regions of land or sea; and good penetration in built-up areas. The band offers high data rates, making it extremely suitable for machine to machine (M2M) applications.

Having high gain (11dBi peak) and wide area coverage, with a 90 degree beamwidth the SA11-90-0.6VH/2178 antenna can be used stand-alone to provide sector coverage. Used in a configuration, four units are required to achieve 360 degree coverage. With appropriate power dividers and phase-matched cables, several antennas could also be stacked vertically, producing a narrower elevation beamwidth and increased gain. These are available from Cobham.

Cobham has integrated both sets of the polarised elements within the same vertical aperture producing a compact, lightweight and rugged antenna. With a UV resistant radome it is designed for long term deployment. Having dimensions of 1550 x 550 x 232mm and approximate weight, including mounting kit, of 20kg, this means shipping costs can be reduced and ease of installation increased.
