And odd way to reduce noise in coax.
Cold wire is a better conductor.
Besure to ground the coax Burr |

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! "download.com" wrote in message ... Cold wire is a better conductor.

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. Ian. -- |

Drill a couple of holes in the freezer part of your refrigerator (or a
freezer,if you have one) Route your coax cable through the holes and seal it up real good around the edges of the holes.(you wife will probally say,,,, Oh h..l NO! you are NOT! either!) cuhulin |
