Right. I was thinking antennas... don't ask!

< coaxial cables with velocity factors of less than 0.10 are used.
< These cables are extremely expensive and somewhat fragile, as their
< center conductor is a coil around a ferrite core,
< rather than a plain copper wire.

Over the years I've made my own delay lines for various projects. Tedious
but saves a bundle!

Common use was delay for vertical on O'scopes, radar (calibration!)
and dram timing.
