The mounting method looks pretty like it distributes the moment pretty well, so not sure if you need to do additional calculations there.
considering my 86" antenna has a lateral thrust of ~40 lbs at 100mph, what would be the bending force at the base if I added another 6 feet?

EDIT: answer my own question: an extra 6 ft would give me 40lbf @ 10ft is 400ftlbs.
