Agreed. On the other hand, investing hundreds of dollars in coax and
rotator cable protectors won't help in this case either. It's not just
single-point grounding, either, but single point low inductance grounding,
which may or may not be possible depending on where your station is
located. In a second floor ham-shack, with no possibility of
low-inductance grounding, I am comfortable that disconnecting every
conductor from the tower is about as good as I can do. On some level of
probability, I may still get damage, but I think this is a legitimate,
cost-effective way of lowering the risk.
