Richard, do you mean that if the coax had been left connected to the dipole
it would have afforded common-mode protection? I think I understand what
you're saying but would appreciate you tying that principle together.
Thanks.

Hi Jack,

Ask yourself "Where is ground in this picture?"

THAT is the Common of the Common Mode. I see it discussed nowhere in
your description. There is the inference of it being back in the
house (code requires it) where lightning eventually found it, the hard
way.

As you describe it:
The coax in question was disconnected about 150' from the house,
disconnected where, how? Up the tower? At the bottom of the tower?
Is the tower grounded? Does the tower ground meet code in being tied
to the house ground? Is the coax grounded? Where? Does it supply
ground? Where?

The Drake was the luckiest of the second-story ungrounded shack gear.
No ground? There are two problems with this statement.
1.) It is unlikely due to code;
2.) It means you accept Common Mode problems.

It being unlikely does not mean you are protected (experience proves
this), it means you went with the flow - of several KV.
