Center-Fed-Folded Dipole for the 66-85 MHz Band

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