MAXRAD's 2.4 GHz ISM Antenna

This new antenna supports 2.4 GHz ISM wireless internet and is designed to let system planners contour coverage and to be less susceptible to interference from adjacent antennas.

MAXRAD's XtremeWave MSO24014PTNF is a new antenna solution that supports 2.4 GHz ISM wireless internet coverage. According to the company, the technical design of its new sectorized omni antenna provides advantages over standard omnidirectional base station antennas. The all terrain sectorized omnidirectional antenna is designed to provide pattern shaping flexibility so wireless internet network planners can apply electrical and mechanical technology to a single antenna model.

The XtremeWave is designed to allow individual sector adjustments of up to 15 degrees of uptilt or downtilt which should let system planners contour their coverage area according to the geographic conditions of the territory. When each sector of the antenna is individually fed, isolation of 40 dB should be achieved and lower sidelobe levels obtained. MAXRAD claims that the resulting signal will be less prone to interference issues from adjacent antennas that may affect gain and reduce overall system performance.

For applications with more specific coverage demands, the antenna is designed to offer more than 10 different azimuth (horizontal plane beamwidth) pattern options that are optimized to address varying coverage, cost control and tower space limitation challenges.

As an internet service provider's subscriber base grows, the MSO24014PTNF is designed to be able to accommodate increased radio capacity with individually fed sectors, which should result in higher gain output (14 dBi) and enhanced throughput capacity with a VSWR of less than 1.5:1. The design may also prevent system failure by allowing installers to remove the damaged components within a section of the array without interrupting service to the other operating sectors.

The XtremeWave's patent-pending mount design should permit installation directly around the tower leg (1.25" to 1.75" diameter), which will minimize windloading on the tower and add mounting flexibility where space allocation is limited. The antenna includes a 1.25" diameter pipe that accommodates center pipe mounting.

The antenna itself is light and compact, measuring 19.75" long and 5" in diameter, and weighing only 8 lbs.
