I agree with the above, but that's not what the original poster wrote.
He wanted to run a separate wire from the tower ground to the house
ground. I think that's a bad idea since it gives a lightning strike to
the tower another path into the house. Because earth is not a perfect
conductor, the entire house ground will be elevated above true "earth"
ground. Not good. 

In my case, I have connectors installed in all coax and rotator cables
at the base of the tower and I disconnect them when lightning is
around. There is no path into the house, so why add one by running a
ground wire from the tower ground to the house ground?
