[TowerTalk] Need bolt hole pattern for Rohn BPH-25G

[Bill Aycock]

John--
I have one, in use. I can measure it, but not 'til tomorrow, I have a short 
trip that will take most of the day. (short trips always do).
If my memory serves me, only cursory leveling is needed; the nuts let you 
fine-tune it.
