Balun for a yagi

The balun is to keep the current in the antenna balanced which the gamma match will not to. This tends to skew the pattern of the antenna if the current is not balanced on the antenna elements. I've not really noticed any problems with pattern skew, though I have no doubt that it occurs. I suspect that it would be more of a issue with phased arrays. Works well enough on EME arrays when I've built them from Cushcraft Boomer parts kits. tom K0TAR |
