Model ADY-156-162 156-162 MHz 15 dBi Gain 
 

MARINE BAND ANTENNA

Design Features : Antenna Experts dual stacked yagi antenna design reflects innovative modern antenna construction and designed to increase 3dBi gain in same direction. 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, power divider and phasing harness cable as standard accessories. A cross-over mounting bracket is also supplied with the antenna to mount the central stacking pipe of dual antenna on mast/tower. Antenna Experts yagi antennas are highly suitable for GMDSS communication equipments used to increase maritime safety and make it easier to rescue distressed ships, boats and aircraft.

Constructions :Radiating elements and supporting booms of dual yagi antenna have been constructed in high quality 6063T6 ultra corrosion resistant architectural aluminum alloys to prevent corrosion. The mounting hardware of dual stacked yagi antenna is made of type 316 marine grade stainless steel. 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 is supplied with powder coating finish to protect against severe environmental conditions 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 beam-width in desired plane.
