Reference grounding. i am gonna bet that that the access head that you have all the coax coming thru is grounded. So all you need to do is ground to that. Not that it will matter for a direct hit.

The conduit is grounded to a huge piece of copper down stairs. I have no idea where that copper runs but it likely finds earth somewhere.
The amp radio and tuner are electrically grounded in the radio room.
What would I ground to from the conduit upstairs? The mast will likely end up being fiberglass.
