Any ideas on where I can buy a super freezer?
Like I said this is an odd way to fight noise.

Look at the Date of the article....... April 1, 2001....... Hmmmmm.

I think that most of us HAVE realised that the article IS a bit of a
spoof. Some just took a bit longer than others.

However, cooling the coax WILL reduce the thermal noise generated in it
and WILL also reduce its loss. Am I wrong, but in radio astronomy, don't
they sometimes minimise the noise figure by cooling the LNB and the
feeder with liquid nitrogen? Again, please correct me if I'm wrong.
Ian.
