	Agree. Our runs have always been 100' or less. We have spreaders from a
military installation, that as a brand spanking new 2LT we supervised
the dismanteling of, and salvaged many many antenna insulators and
spreaders along with a lot of wire.

	The wire is interesting. No. 6, 3 strands of soft drawn copper around 1
strand of copperweld for strength. The spreaders are 15" x 3/4" dia. and
the insulators are 2" x 1" x 16" porcelan.

	Military and commercial always did things up in style though.
