Jeff:
I agree with Tom - don't use the chimney to mount any appreciable-sized
antenna. The chimney may look sturdy but mostly they are three sides of brick
that are attached to the house with galvanized steel straps layed up between
the mortar layers and nailed to the house walls. A good wind blowing against a
decent size antenna load above the roof could push this entire chimney assembly
over onto the ground. As others have suggested, a roof-top tower, properly
tied into the roofing trusses, would be a much safer alternative.

Hi Jeff
Don't think mounting on a chimney is a good idea. Most are brick and mortar
and are not very sturdy. Probably a small roof tower would work better. 73
