Thanks for the two answers above. Both respondents favor a tripod install. As I indicated previously, that seems to be the preferred method on Denny's site (Hd Stacker, etc.) too.

I had hoped that there would be a comment or two regarding other methods. While I don't disagree that a tripod install done properly is stable and reasonably inexpensive, the ground level to peak mast has real appeal. No roof damage, inexpensive, and hopefully stable if done right. Three 10' 6" swedged 17 gauge poles from home depot installed about 2' below ground and held by two or more 4" wall mount brackets should run about $50. I already have a bag of concrete mix left over from a previous project. Using this method, the grounding cable would be short and inexpensive as well.

I'll reflect on this a bit more. There may well be valid reasons why all votes are for the tripod.
