Normally, phase matched cables are all made from same coax drum. Ensure coax

Hi Both,

This has all the hallmarks of a mutual suicide pact.

The right source for matched lines is from a vendor such as:
http://www.micro-coax.com/pages/prod...axialCable.asp
where a specific example has sub percent tolerances:

And the question remains:
"What is the degree of matching?"

The answer to this spans cables from Radio Shack, to the provider
offered above who specializes in precision.
