John, your set up for protection sounds pretty good, but 16 feet between
ground rods is a half wave at 10m,  and  a quarter wave on 20m, so watch for
any RF in the shack issues on those bands.  It may be just fine, as a half
wave repeats whatever impedance it sees at the other end, but I try to stay
away from lengths that fall into ham bands.  The band of most concern is
where you have a quarter wave ground length, and that is 20m, but the
effective length should be from rig to first ground rod.  Sometimes, you
just cannot avoid some length getting ground outside the shack.
73, and GL,
