[QUOTE="Channel Hopper, post: 549185, member: 175144"] Exactly. What is interesting though , is plotting the signal reception of a weak signal when the LNB is heated to variying temperatures, as this can be used to provide a curve on a graph that determines what is the likely advantage of cooling to extremes. It is not just the noise figure that is altered, circuit stability and the power supply components all undergo degradation away from their standard specifications. What is the point then, if the advanteges are so small. As others have stated, it may not be to everyones taste, but if you are already out of other solutions, and you have a fridge, and the wife does not object to it being taken apart and some plumbing added, you can get a few channels that might not normally be received.
