BASE STATION ANTENNAS BD2 1G W

Center-Fed-Folded Dipole for the 144-174 MHz Band

Single, 0 dBd folded dipole incorporating a balun optimized for wide bandwidth and accurate matching. The entire
balun unit and feeder terminations are completely sealed in a polyethylene (�ET) moulding ensuring permanent
waterproof connections. The dipole have been constructed with high-quality aluminum to prevent corrosion. All
metal parts are DC-grounded. The antenna is supplied with clamp for mounting on 27-50 mm diameter mast
tubes.
