That book just shows you how far we have come in understanding since it was written. These days it is a curio and even Low Band DXing by ON4UN is in its 5th revision.
When I first tried a 2 wire Beverage in the early 80's I found that nothing worked as published and persistent questioning him got me nowhere.
I have two different versions of the BA Handbook. The last time I studied them, I didn't find a single thing in there that was useful. I almost threw them both away.
I think you'll be a lot happier with a Beverage design from ON4UN's latest book.
