Dan. It's usually a bad idea to put an antenna on a chimney because of structural considerations. The force of wind on the antenna will place part of the chimney in tension. Mortar joints aren't very strong under that condition. I have seen chimneys destroyed from an antenna mounted on them.
As far as grounding I would try to ground the antenna mast to the electric meter ground. Some local electric codes forbid that so you should check into it. If they do, you need to drive one or more ground rods into a patch of dirt that gets watered frequently. The ground under a deck will dry out and not give a very good ground. When you count 10 or less between lightening and thunder you should turn off your set and disconnect the antenna. Regards. Max. K 4 O D S.
