[TowerTalk] [CQ-Contest] Stacking on separate towers, take off angles?

[john at kk9a.com]

I thought that W6KPC had a single tower with horizontal and vertical
stacked yagis.

Frank, W6KPC, had multiple towers with yagis in 'echelon' phase.

There was an article in QST many years ago, with a cover photo.

Someone might be able to do a search and find the article.
