HIGH GAIN DUAL STACKED YAGI ANTENNA
Design Features: Antenna Experts dual stacked yagi antenna design reflects innovative modern antenna construction. The dual stacked yagi antenna uses special feed which eliminates the use of folded dipole. This ADY-350 dual antenna system comes in pre-assembled design with permanently fixed elements in to the support boom and does not require any field tuning or adjustments. The dual stacked yagi antenna is supplied with a stacking pipe and phasing harness as standard accessories.
Constructions: Radiating elements and supporting booms of dual yagi antenna have been constructed in high quality aluminum alloys to prevent corrosion. The unique design of the yagi antenna feed which works as matching device to keep the VSWR low resulting in increased efficiency of the dual yagi antenna. The antenna can be mounted to obtain any horizontal or vertical polarization. Similarly the antenna can be stacked either horizontally or vertically to control the beamwidth in desired plane.
