OK, this is what I thought, but wanted to make sure there wasn't something 
obvious that I'm missing. 

I don't yet have a nice, grounded, copper-plate bulkhead through which I feed 
everything, but I'm working on that.

Yes, I know well that lightning does pretty much whatever it darn well pleases, 
and I am unhappy leaving it all floating. Right now, it's about all I can do, 
and that has to be better than leaving it all connected (been there, done that).

Thanks for the info and sanity check!

Your best choice is to ground those cables where the enter the house at 
the bulkhead panel which should be grounded.  You definitely do not want 
to let them float.  Here the coax comes in through bulkhead connectors 
in the grounded bulkhead where the Polyphasers are mounted. Normally I 
do not have the option of disconnecting any equipment including 
computers and network connections and all that interconnecting wire 
makes a good inductive pickup. Photo next to the 
bottom and on the left hand side shows how I've been doing it although 
the photo is badly outdated it still conveys the idea.
