This was a decision process I had to also go through when I installed my
tower-mounted Ameritron switch.  The problem then becomes how to ensure
that lightning doesn't follow the control cable down into the shack.

Polyphaser also makes shunt protectors for 8-conductor cable.  I used one
at the top of the tower and another at the ground window entrance to the
shack.  For a photo of the ground window, see the bottom photo on
http://www.qsl.net/w6old/partyinstall.html.  There are two of these control
cable shunt protectors in the top right corner.

73, Dick
