[TowerTalk] Size of Concrete Base?

[k8rs@acd.net (Roger C. Stimson)]

Steve,
          I have just purchased a Titanex V80 HD vertical antenna.  It
is 68' x tapered 4 " to 3/4" aluminum and is designed for a
self-supporting installation.  However, Titanex has not provided any
engineering drawings for the base which is made of two 3" x 2" x 6' 9"
galvanized steel c-beams.  Is there a source for determining the size
concrete foundation for such an antenna?
           Thanks,
                        Roger K8RS
