BASE STATION ANTENNAS 7-element Yagi Antenna for the 380-470 MHz Band with 10 dBd Gain B Y 7 0 -10G W

This is a 7-element Yagi antenna with 10 dBd �ain. This Yagi incorporates baluns optimized for wide bandwidth and
accurate matching. The entire balun unit is completely sealed in a polyamide (�A) screw cap 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.
