Do you happen to be in Wa. state?
I have a 1k spool of lmr400 I could let you take measurements from :-).
Probably still have 200ish feet on my "small" roll.
I've also got various hardline cable (5/8", 3/8" and some 1" I think.).
Mostly under 100' runs. Came off of a tower, old gear that I never used so
I'm not exactly sure what's there.
