 Model ADY-150 134 - 174 MHz. 15.5 dBi. Gain 


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. The dual yagi antenna when packed comes with elements removed from the antenna boom for ease of packing and transportation. This yagi antenna can be assembled at site with simple hand-tools. The dual stacked yagi antenna is supplied with a stacking pipe and phasing harness as standard accessories.

Constructions: Radiating elements, supporting booms and adjoining metal castings 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.
