Thanks Jim,
I had already read your articles too. This will not be a multiband
vertical. Just a simple, resonant 40M 1/4 lambda vertical that will sort
of work on 15 as well, although with higher launch angles.

You might also find these two sets of Power Point slides useful.

Also look at the link to AD5X's work on the 43 ft vertical. And by all
means buy and study the K7LXC / N0AX report on their measurements of
various verticals. Based on their work, If I needed to put a multiband HF
vertical on my roof, it would be one of Cushcraft R-series, like the R-8.
