Hi David,
Check out the "ARRL Antenna Compendium" Volume 2 page 10 for a good two
vertical
array project. It will work well with multi-band verticals too.

Subject: [TowerTalk] 2 Vertical Array Question
All the 4sqr talk has inspired me.
Given that, because of space constraints, I'm ONLY looking to install a 2
vertical array (on 40m in this case, and projecting it to be switchable),
please debate the merits of the "cardiod" pattern by feeding 90-degrees out
of phase (3db gain by the ON4UN book and best f/b) and possibly feeding
135-degrees out of phase (4.9db gain by the book and small back lobe)?
It's a gain vs. f/b question. Thoughts?
