           3-element Yagi Antenna for the 66-85 MHz Band


           This is a 3-element Yagi antenna with 5 dBd Gain. The antenna is terminated with N (female) connector. Radiating   BASE STATION ANTENNAS
           elements,  supporting  booms  and  adjoining  metal  castings  are  constructed  in  high-quality-aluminum  alloys  to
           prevent corrosion. All metal parts are DC-grounded. A mast clamp is provided for mounting on 27-50 mm diameter
           mast tube.
