My name is Rick, not Karl.  Anyway, we basically don't get lightning
in Galt, so I don't worry about it for the Beverages.  They are far
more likely to get eaten by critters or broken by me walking into
them, etc than struck by lightning.

I use DC not AC on the coax, BTW.  The DC is both the signaling voltage
and the power voltage.  Each relay has a dropping resistor so
it is happy with the voltage that is there when it is activated.

I antennas all over 20 acres.  Remote power is out of the question.
