Eighty-five years ago, both daughter and Fido were helping Dad install a lightning arrestor for the family radio antenna. Dad noticed that the spark plug from a Model T Ford could screw directly into a 3/4 inch water pipe fitting. So he added a tee to an outdoor tap, screwed the spark plug into the other end, and attached the antenna.

The magazine noted that the same thing could be done with a section of pipe driven into the ground.

This item appeared in the April 1939 issue of Popular Mechanics.
