Everything inside the house should reference the ground and neutral at the 
service entrance or breaker panel.  Since there is supposed to be a driven 
ground at the service entrance, I could care less about the fire hydrant or 
well casing.  Water lines are no longer accepted as a suitable ground for 
anything.  And if your well casing is plastic, as many are today, it is 

However, more important, all driven grounds on a property served by a single 
service entrance, must be bonded back to that service entrance ground. 
There's no exceptions to this rule.  Failure to initiate this procedure 
produces a highly dangerous condition.

As to having a RF ground,  a ground radial system below your antenna is the 
reference point for that antenna.  Several antennas can share the same 
radial system.  Also that radial system must be bonded back to the service 
entrance ground.
