I have to transport four U.S. standard 5/8" dia x 8' long ground rods
35 miles in my four door compact car. Do not want to carry them on the
roof. If I cut them to six feet long I can load them inside the car.
Ignoring any code compliance issues would there be any reason the
shortened rods would not work as well as full-length rods for purposes
of ligtning protection and the usual HF station RF grounding? Soil here
is probably very conductive (damp heavy loam). Thanks.
