The transient arrestor should be at the building entry, again to keep
lightning energy out of the house. Putting another one inline somewhere else
is a waste of money because you only need one inline at the Single Point of
your ground system. While having one on the tower would take care of
transients coming down the cables at that point, you've still got potential
problems between there and the building entry so the one on the tower really
doesn't do anything.
