Thank you for responding to this, Gerald. I was going to call you folks
this week to see if you folks could shed any light on this.
Radian doesn't publish specific dimensions (that I know of) on the
BPC25G (pinned base plate) and 25GSSB (self supporting base plate) but
by their shipping weight, I can see the they are vastly different
products. The self supporting base is twice the weigh of the pier pin
base. The extra steel would account for the extra cost. One can't
simply purchase a BPC25G, drill four 11/16" holes in it and call it a
SSB25G.
The Rohn/Radian specs spell out very clearly that the BPC25G is not to
be used for a bracketed tower. They call for a short section embedded
in concrete, or either the 25GSSB or BPH25G. My guess would be that
many who wish to use a base plate with their bracketed tower either use
the pinned base plate anyway or drill four holes in the pined base plate
and call it a self supporting base plate. I haven't worked with enough
25G towers nor have I paid attention enough to know if this is true --
just a suspicion.
Thanks to everyone who has emailed me!
