  Hi Jim,

If you have the financial means, the shields of tower coaxial
transmission lines should be bonded to the tower at or near the top AND
bottom. The idea here is to shunt as much of a strike's transient
current to the tower as possible (the metal conducting mass that can
handle the current), then effectively drive as much of the transient
current into the bonded tower and building ground system as possible -- 
before it enters the building and contained electronics.

     Joe and I posted this 
http://lists.contesting.com/archives//html/Towertalk/2007-10/msg00356.html a 
while back about how we made our own coax shield connectors for just this 
purpose.  The expense is low enough that there ought to be no reason not to 
do it.
