I thought we settled this yesterday. The antenna mast should be
connected to a ground rod. The cable should have a lightning arrestor
connected to a ground rod near where it enters the building. If
either one of these is too far to be easily tied to the existing
ground, then I would use seperate grounds.
At 7 ft, it's not nearly the risk of a chimney mounted mast, but it
still has some risk, and I would do it right.
