Hal, Good point.
and I have never seen a spec for phase stability for Cat-7 cable !
for RG58, OR OTHER polyethylene, might be up to 150ppm /deg C. maybe as
good as 10 ppm/deg C for some LMR.
With 1000 feet of cable might be an issue for fine stuff. a few nano
seconds each way over temperature might not matter for his project...
I forget it is not a microwave RF VNA application. Easy to resolve
anyway with a difference balance term somewhere.

coax cables are in general NOT PHASE STABLE with temperature, either.
Is twisted pair any better?
