The CDF80 centre fed dipole radio antenna is manufactured to a high degree of Telecommunications specifications. All the dipoles for the CDF series are fabricated from one piece of tube, this has been done to alleviate the possibility of any high resistance points that could become present in a dipole that is made from more than one piece. The internal balun is completely seal moulded in black carbon-loaded polyethylene. These antennas are ideal for wide band applications and can be stacked vertically and fed in phase, using two/four dipoles, a gain of 3dB/6dB respectively can be obtained.
