@stvcmty, thanks for the kind words.
As I re-read my earlier post, I see that it would be easy to think I was favoring the addition of a ground rod. That is not the case. I was focused on addressing the question of adding an un-bonded ground rod which I believe should be avoided in virtually any circumstance.
Thank you for clearly stating 'best practice'.
As an aside, I believe it may prove to be less costly to run #10 AWG copper from the mast to the electrical service even though the coax run may be longer as well. Ground rods, bronze connectors and #6 AWG copper aren't being handed out as door prizes at my local home center.
