Agreeing with ADTech...
Ideally the mast ground would run from the mast to the electrical service ground, not connected to, or combined with, any other ground along the way. As ADTech has said, #10 copper is the minimum size wire mentioned in the code.
Ideally the coax ground block will be connected to the electrical service ground via a separate wire, again, not connected to, or combined with, any other ground along the way.
If you decide that you are going to add a ground rod, it needs to be bonded to the existing electrical service ground system. In most residential situations, a #6 copper wire is the minimum size for the bonding conductor.
Even if your solar system is grounded properly, it's not a suitable alternative for a direct connection to the electrical service ground. Combining or interconnecting the grounds of the antenna and solar systems impairs the effective protection for both systems.
(Emphasizing that best practice is to treat the mast ground and coax ground as separate and distinct from one another.)
