My house -- a farmhouse -- came with an array of 6 lightning rods, complete
with woven aluminum down-conductors. Lightning rods are fairly common on
houses out here. I am very unclear on whether they offer any protection at
all, because the ground conductors seem to violate the low-inductance
requirement that we hear from Polyphaser. It's not clear to me why
lightning would "prefer" the rods to other ground conductors that might be
available in the neighborhood, or on nearby power poles.
