DUAL STACKED YAGI ANTENNA
SDY-85016 800-990 MHz 16 dBi. Gain


General:
This robust, heavy duty and all weather Dual Stacked Yagi Antenna is manufactured using aircraft Quality high grade anodized aluminum tubes and rods. The Dual Stacked Yagi Antenna is supplied with a stacking pipe as mounting accessory. The phasing harness cable with molded cable joints and N-Female antenna termination is also supplied with the antenna. The installation requires no tuning or adjustment of stacking distance resulting in the installation of dual stacked yagi antenna an easy and simple job. This Dual Array System comes in pre-assembled design with permanently fixed elements in to the support boom and does not require any field tuning or adjustments.

Design & Construction:
The antenna uses a ‘SLOT’ design in conjunction with air-cored co-axial section forming the part of the boom for impedance matching completely eliminating the use of reactive components and is terminated into an N-Female socket at the end of the boom. The slot is sealed with a “die-mould” for weatherproofing. The tuning over the entire bandwidth is achieved with the use of a ‘STUB’ matching transformer enclosed in the boom. The unique design ensures a streamline look to the antenna and has no external part attached to the antenna-dipole for tuning and matching. The antenna is D.C. grounded for noise immunity and lightening protection.
