I must strongly disagree.
By disconnecting cables inside your shack in lieu of (instead of) any
lightning protection, you are leaving your house open to a fire started by
the arc-over from lightning in any open circuit cable from the outside
(SO-259, telephone line, dangling PL-259, etc.) I think it's just stupid to
just disconnect the equipment and not have Polyphasers or other similar
device on each cable entering the house.
I keep all of my equipment connected all of the time, including IC-781 (with
Beverage and HF antenna cables connected), IC-4KL, 4 PacketCluster radios, 6
rotor control boxes, PCs, telephone wires, etc). I have a 24/7 fully
If you've seen my website www.erols.com/n3rr , you know I have substantial
lightning protection installed.
