Almost, anything but a disconnect.

Also, while we sometimes go wild with grounds, nearly ALL of the protection 
(or lack of protection) comes from how things are bonded and common grounded 
going into the protected area.

I can't stress the point that a proper entrance and proper ground bonding, 
so everything rises together without high current loops through equipment, 
is nearly 100% of actual protection.

My towers take at least one hit in every lightning storm, and other than RF 
ground radials on my four square area, I have no fantastic grounds. My 318 
foot tower has eight deep-buried number 6 or 8 gauge copper radials about 
50-100 feet long, interspersed with around thirty  #16 shallow bare wires 
from when I fed the tower as a vertical. It has only a few ground rods.

The house has a buried perimeter conductor, but almost no ground rods.

I never have lightning damage inside buildings.  Not one piece of consumer 
gear has ever been damaged. Never lost a modem.

Despite what we sometimes hear, nearly all protection comes from how 
entrances are constructed and bonded. The worse thing in the world is an 
entrance ground that is not connected to the power mains ground.
