Yes.  Better if you ground it, though.

More reason for grounding the coax/feedline end.

No.  It's faceitious to believe that.


it's better than doing nothing and leaving the equipment connected.

Most lightning strikes are simply "nearby" strikes.  Those nearby
strikes can carry a lot of energy to your antenna system, energy that
can damage equipment.  It's the nearby strikes that disconnecting will
likely protect against most often.

The direct strike is probably a lesser likelihood and certainly can
cause more damage than a nearby strike.

At least, by disconnecting (and grounding), you have hopefully reduced
the chances of being affected by a nearby strike or even a direct

If you wait until you hear the storm's thunder, you are certainly
putting yourself at risk.  That's why I say that whenever you are not
operating, disconnect everything. Then, you don't have to worry about
racing the storm to your feedlines/ac power, etc.
