    Temperature influence?

    Does the low temperature influence the signal strengh? I don't mean clouds, snow, rain etc., only the low temperature?

    Low temperatures should give better signal, I mean better quality (not strength), because lower temperature means lower noise in signal amplification in LNBs.

      in my experience the low temperature does not affect the quality of the signal

        Of course I am talking about extremes ... only when it's summer and very hot, with clear sky, I have some channels showing BER > 0.

          It's possible only when temperature is very high or very low because it's an out-of-range temperature or if you have ice on your dish or onto lnb.
          I don't find temperature range into datasheet of my lnbs, but I think they are made to be compliant with industrial standard. Into industrial environment the accepted range is -25°C to +85°C.
          A good lnb work without problem into range -25/-30°C to +50°C.

            Signal strength is indeed dependent on temperature, colder
            temperatures will lend to higher signal strengths the only way
            temperature might have an effect is if you get a a good layer
            of frost on your dish and LNB.

              There was a story about a German man living in Brasil I think it was who was able to receive signals from Germany, he was using a super-cooled LNB on an admittedly very big dish to do this, so yes temperature does play a part, but only at extremes I think and not for normal use.
