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.
