Default Balun for a yagi

I've tended to prefer a gamma match... its far more flexible in terms
of matching and does the balanced to unbalanced conversion as well.


The gamma match does not seem to be thought of as working very well at vhf
and above. Also it defeats some of the purpose of a balun on a beam. 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 ballanced on the antenna elements.
