I'm planning to install a 70-foot Rohn 25G tower and need advice on pouring the base. Recommendation is concrete poured at 2x2 feet 4 feet deep with rebar. The tower base will be located approximately 2 feet from my house foundation, which is wood-framed (6" walls clad with plywood and waterproofing materials). The house foundation extends 70 inches under ground level near where the tower base will be placed.
My primary concern is: If properly guyed, could tower sway still cause the tower base to impinge on, push out/in, or otherwise impact the house wall/foundation, given how close it is?
Are there guidelines or considerations for minimum safe distance from a wooden house foundation when placing a tower like this? I've never seen anything like this foundation before.
Any advice or experience with similar installations would be greatly appreciated!
Thanks in advance.
