[TowerTalk] Foundation for new tower

[Bob Henderson]

I am starting to make plans for the erection of a second tower and hope to benefit from the experience and expertise of towertalkians.

My immediate questions concern the specification for a foundation to support the tower and likewise for guy anchor points.

I have 10 x 10ft sections of tower which appears similar to Rohn 55G.  These sections measure 19.5 inches across the face with legs of ~1.3 inches diameter.  The cross struts are ~0.44 inches diameter.  I have two further tower sections 15.75 inches across the face with 1 inch diameter legs and cross struts of ~0.35 inches.  These connect to the larger tower sections with a jointing collar.  I propose to use a pier pin arrangement at the base of the tower.

Can someone help out with appropriate specifications for the tower base and the anchor points?

Thanks
