Having modeled and built a very large number of 2-element Yagis over the years, I thought a refresher might be in order, if only to clarify what count as reasonable expectations. The information is available in almost any solid reference, but perhaps a different type of presentation might by useful. If this is your first entry to these notes, I recommend that you read the parts in order.
The refresher is long and broken into a number of sections. It is at present unillustrated, but contains extensive tables. Illustrations may be added later, time permitting.
