2-element Yagi Antenna for the 144-174 MHz Band with 3 dBd Gain

This is a 2-element Yagi antenna with 3 dBd �ain. This Yagi incorporates baluns optimized for wide bandwidth BASE STATION ANTENNAS
and accurate matching. The entire balun unit and feeder cable inlet are completely sealed in a polyethylene (�ET)
moulding ensuring permanent waterproof connections. The antenna is terminated with N (female) connector.
Radiating 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.
