I do have the ARRL Antenna Compendium volumes, except for Vol #5 and #7, so
I'll look through those to see if the article is in of of them. Someone
mentioned mounting the couple of verticals above a metal roof, but my garage is
a typical "Stick-built" construction, with 2X6 construction, composite shinge
roof, and effectively no metal. I'll have to use tripods, radials, etc.
