A transmission line balun (50) comprising a tubular ferrite (52) having a longitudinal passageway concentrically positioned over a conductive sleeve (56) having a longitudinal passageway. The end of a coax feeder (24) is positioned in the longitudinal passageway of the sleeve (56) and the sleeve (56) is grounded at its proximal end to the shield (18) of the coax cable (14). The sleeve (56) buffers the effects of the parasitic line caused by using ferrite (52) in a balun (50). |
