Does an UnUn decouple an antenna from the feedline?
wrote:
I am trying to figure out the proper balun to use on an Off Center Fed dipole I am going to construct. I have settled on a 6:1 UnUn design by Jerry Sevick, W2FMI. My question is will this properly prevent feedline radition? Is some feedline radiation always expected / inherit in this type of antenna design? The two different legs of the OCF dipole have different impedances so it is virtually impossible to balance both the voltages and currents into each element. If you install a choke about 22 feet down the coax from the feedpoint, you will have duplicated the Carolina Windom which takes advantage of the inherent feedline radiation. -- 73, Cecil http://www.w5dxp.com |
