It will be of interest that if the inner conductor of 600 ohm coax is 18
gauge wire then the outer conductor diameter will be 22,000 times greater.
ie., about 72 feet.

Not surprisingly, an 18-gauge wire at a height of 36 feet above ground has
an impedance of the same order. Isn't it reassuring to see how things all
fit nicely together.
