Radio Frequency Systems (RFS) will unveil its all-in-one rooftop antenna solution - the Optimizer Rooftop - at the 3GSM World Congress 2007 in Barcelona.

Intended to strike the optimal balance between aesthetics, RF performance and capex / opex, RFS believes the Optimizer Rooftop is set to "transform urban rooftops the world-over."

Optimizer Rooftop comprises a 'star configuration' base, mast, tri-sector antenna cluster and RF cabling. It is designed to tackle a very real problem at the heart of any modern network manager's most vexing problem: visual impact requirements often prove to be the Achilles heel of urban site acquisition and site renewal negotiations.

The mast is a 75 mm-diameter structure that tilts into place and supports both the tri-sector antenna cluster and optional RF conditional module. The low-profile antenna cluster houses three RFS Optimizer family sector antennae which are each designed to provide a full +/-20o of azimuth adjustment - a vital feature in modern network management.

Three Optimizer Rooftop models will be available upon release: 3m- and 4m-high fixed-height models, plus a telescopic 4-5.5m version. At initial offering, the Optimizer Rooftop will be available with a choice of nine different RFS Optimizer antennae. These encompass the Optimizer suite's broadband, side-by-side, triple-band and dual-band antennae, spanning frequency bands from 900MHz through to 2,200MHz.

Optional fully integrated tower-mount amplifier (TMA) modules designed to house up to three TMAs or boosters, plus antenna tilt control units (ACUs) are also available. Antenna Interface Standards Group (AISG) v2.0-compliance is another feature of these active tower-top components.

Optimizer Rooftop is tailored for buildings of four or more floors, and typically exerts a rooftop pressure of 150 kg/m2. It is claimed to retain its stability in winds of up to 150 mph (250km/hr) without concrete ballast. Maximum component weight is 60kg and maximum length 2.2 m. Optimizer Rooftop will also absorb add-ons such as microwave antenna, remote radio head ('fibre-to-the tower') solutions, and a growing suite of WiMAX-ready antenna solutions.
