Hi Steve,

I answered exactly this question several years ago with an extensive 
modeling study motivated by the work that you and Ward did 20 years ago. 
These link are to slide decks for talks at Pacificon. The first 
addresses verticals, the second horizontal antennas.

This is the link to a piece I wrote for NCJ that addresses both.

The short answer is that on the roof is better, and that the design of 
some verticals is such that they don't need or benefit from radials.
