Default And odd way to reduce noise in coax.

Cold wire is a better conductor.

Besure to ground the coax

Yea but if its not absolute Zero it isnt better

-459.67 °F

If you have moisture or water in your coax then getting it below freezing
definatley does help! Ice wont conduct RF or electricity!

I've seen this hundreds of times working for a cable TV company...When the
WX gets frigid TV clears right up!

After 43 years in the cable TV industry, the old memory is beginning to
go, but I reckon that the coefficient of loss change is 'point two Ohs
two per dB per degree C'. Correct me if I'm wrong.

In the UK we don't have so great a problem as in the US. Coax is
invariably buried (never slung on utility poles etc), and the
above-ground extremes of temperature are much less.

And if you use dry ice to cool your coax, you shouldn't have moisture
ingress problems.
