I took a hit a year ago in September.
To make a long story short my ham desk now has 3 connections:
- A single Coax
- 120v
- 220v
All antenna switching and rotor control is via Green Heron Everywhere
wireless interfaces. My rotor boxes and switches can still take a hit
but the equipment on the operating desk won't, as long as I disconnect
the 3 items listed above. I do use power poles on my control cables so
I can quickly disconnect the 3 rotor boxes from the outside world as
well, I just need to remember to unplug them from power.

I don't know if this really helps or not, but I connect my computer to the
internet through a WiFi. I have DSL which feeds a WiFi Router. That DSL
modem and the router are the only things connected to the phone line.
When lightning threatens I disconnect all power, ground, coax, rotator
control cables, etc. Anything that goes to the outside world (including
the station ground to the ground rod outside of my window is removed.
I live on a ridge, the highest point in the county. The ground slopes down
and away for 20 to 30 miles in all directions. I have two 150 foot towers
and a 70 footer. The first ten years I was at this location I was hit 4
times by lightning. Then I instituted my disconnect policy. I have had no
strikes in the last 20 years. The lightning strikes, but there has been no
damage to equipment.
The chassis to chassis bonding remains in place.
Your results may differ.

Hi all;
I am starting to see our yearly peak of Lightning damaged radios come in
for repair, August through October.
It is MOST likely to come in through the COMM PORT connected to your
COMPUTER (via DSL or Cable Modem).
Those lines are LONG and run for miles, so a direct hit is not necessary
to do damage.
Customer quotes; "I disconnected everything, EXCEPT..." then they list
ONE item.
Spare K3 board supplies are low or gone.
Besides the most likely Comm Port, then obvious Antenna, I have seen
lightning come in other things connected to the K3, like;
DC power cord, ground, Paddle/Key, Key-Out to Amp etc.
