Put aside the reference to 'single digit feet' for a moment.

Let's rewind to ADTech first post:

First choice would be on the input to the pre-amp PROVIDED that you have your pre-amp's case grounded as part of a contiguous and unified grounding scheme (single continuous wire running from the pre-amp case to mast to grounding block to structure's ground electrode system)...

Can you run a wire as recommended, from the antenna preamp & mast to the power service ground rod (keeping it all on the outside of the building)? (It will almost always be more that 'single digit feet', no worries.)

Then, is it possible to consider mounting a coax ground block close to the power service ground (this is were 'single digit feet' applies) and then running the coax from the antenna to that block, then into the building?
