Folks,

I'm looking for a formula for Signal-to-Noise ratio for a satellite Rx setup, i.e. where SNR can be calcualted using metrics such as Antenna Gain, Receiver Noise Figure, LNB Noise Figure, Transmission line loss, etc, etc.

Perhaps one of you learned folks can point me in the correct direction? Funnily enough I'm pretty sure that I knew this about 20 years ago during my college days but it's now long forgotten :)

Regards ... Wally
 
Loads of useful calculators here including downlink budget calculators.

Obviously they are only as good as the inputs and weather conditions allow.
