Do you have any construction information available for your TDR?

I usually have the opposite problem with coaxial cable. For example,
I would solder connectors onto a 100ft roll of RG8/u while it was
still rolled tight on the spool. Bad idea. When straightened, the
center conductor becomes slightly longer than the shield. The stiff
center conductor tries to push the center pins out from the
connectors. In one case, I found a mangled N connector pair where the
center pin had shoved its way into the mating receptacle.


Ooooo, thanks for the heads-up. Great comment!

John
