Yes.  They are cheap and I had no idea of what the lightning risk would be 
here.

I've had to do work on the active antennas a few times so I know ground 
level lighting currents are around.  But never had a problem with the 
beverage.  Maybe I'm just lucky.

Jeff,

Do you mean six of the Ohmite type OY resistors in parallel?! I can
understand paralleling CF resistors, but just one of those OYs will take
quite a hit.
