UHF Corner Reflector Array 400-520MHz


The CRA series panel reflectors are based on the popular OA series offset arrays, but incorporate a fully alodined grid reflector. The array features 11 dBi gain, low noise performance and enhanced null fill coverage in an array with typical cardioid coverage characteristics.

CRA40-67 Features:

The CRA Series have 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 polyethylene jacket. The antennas are offered with 0°, 5°, 8° or 10° of downtilt, and all include extensive side lobe 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.
