What does the noise level do? Are we talking feedback on the channel you are watching or how loud the volume for the channel comes in?
I remember as a teen growing up on my parents BUD there was alot of popcorn on some of the channels. (about 16 years ago) Was C band only analog back then?
dB - Logarithmic representation of a mathematical value. It can be used to represent power (dBW), audio level (dBm), gain of an antenna (dBi) and losses in a system (dB).
I started in satellite when there only was analog, snow on the screen was normal between satellites, recently started messing about with analog C-Band again, amazed at the picture quality and I must say I missed the snow
