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.
