Forrest Gehrke wrote a series of articles in the 70's on
the technical details of phasing verticals. I think there were
4 or 5 articles in Ham Radio Magazine. I would love to get copies or buy
the
magazines from someone. He used
to be my qsl manager years ago when I was a DX station. I am now looking
into phasing some verticals now that I have the room to do it. I'd like to
start on 40m.
