Rabbit, I had an antenna guy install the antenna, but, I really don't know what he did as far as grounding. I would have to call him to find out. I am about positive, though, he did not ground anything to the house's electrical box.
Here are two grounding diagrams:





According to Article 810, the last time I checked, the mast can be grounded with 10 gauge copper or 17 gauge copper-clad steel. However, the coax grounding block must be connected to the house electrical system ground with 10 gauge copper wire.

If you use a separate ground for the mast, it must be bonded to the house electrical system ground with 6 gauge copper wire.
