5-element Yagi Antenna for the 380-470 MHz Band with 7 dBd Gain

This is a 5-element Yagi antenna with 7 dBd �ain. This Yagi incorporates baluns optimized for wide bandwidth and BASE STATION ANTENNAS
accurate matching. The entire balun unit is completely sealed in a polyamide mould 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.
