Knut,

For those station installations that have adequate lightning protection 
implemented, it will not be necessary to disconnect anything except the 
antenna.
If one follows the recommendations of Ron Block in his 2002 QST 3 part 
articles on lightning protection, everything in the hamshack area 
*should* be at the same potential during a surge event.  That does mean 
providing protection for *all* lines (power, telco, ethernet, antennas, 
rotor control lines, etc) coming into the station at a single grounded 
entry panel, and bonding the enclosures of all equipment in the shack to 
a single common point which is then bonded to that shack entry grounded 
panel (which also must be connected to the utility entry ground).  Then 
I believe you can leave those miscellaneous cables connected and not 
experience a failure except that all bets are off for a direct strike.
All bets are off if you choose to do an incomplete job of equipment 
protection in the shack too.

The articles I refer can be downloaded from the ARRL website.  Do a site 
search on 'lightning protection'.

73,
Don W3FPR
