Description
These feed elements are constructed from a fully folded dipole welded to the boom, providing maximum bandwidth, excellent intermodulation performance and high reliability. The passive elements are thru mounted to the circular boom section which is fully welded to the mounting tube with a welded spacer between both booms before plating. The entire antenna is then plated in an alodine finish to provide an excellent conductive surface to ensure effective earthing of the antenna when it is mounted. The YBA818-82 can be double stacked into a 4-boom array for additional gain by simply ordering two antennas and the PA84-82 stacking kit which includes 2 spacing control frames, two fiberglass upright supports and a two-way phasing harness for phasing both arrays together. Note: Suitable for vertically polarised installations only
