Description

Features: The CRA Series has slightly more than 130° horizontal beamwidth. The use of the grid reflector boosts the front-to-back ratio considerably making the CRA40 series ideal for tailoring antenna patterns to allow frequency re-use in extended networks. The optional electrical beamtilt allows for significant further suppression of unwanted signals and allows enhanced coverage in the target areas.

CRA Series arrays feature the same solid construction as the standard array series. The folded dipoles utilise an internal phasing harness in PTFE based double screened coaxial cable with a polyethylene jacket. The antennas are offered with 0°, 5°, 8° or 10° of downtilt, and all include extensive sidelobe suppression, null fill and a power input level of 500 watts continuous.

With all-welded construction and superior internal harness construction, the antennas provide not only excellent radiation characteristics but also defined, high levels of intermodulation and noise suppression. IM performance is a world-leading – 150dBC based on a two-carrier test. The entire array rests at ground potential and offers the ultimate in lightning-resistant antennas.

• Offset (cardioid) pattern • 0°, 3°, 5° or 8° of downtilt available • High front to back ratio and use of optional beamtilt to allow frequency re-use by tailoring coverage areas • Extensive sidelobe suppression and null fill • Hermetically sealed internal phasing harness • Industry-leading PIM ratings providing low IM and low noise characteristics for optimum performance
