Lost signal from the satellite
Signal Fade And Loss ~ Important, especially during winter!
Keep in mind that satellite broadcasts occur directly from fixed satellites in space to users. UPLINKS TO that satellite can happen from almost anywhere in the world! This includes broadcasts from remote studios, satellite vans and trucks.
Even signals from the main providing studios are susceptible to weather conditons even tho they have huge, high-gain transmitting dishes!
Weather is a major factor for both the uplinks and downlinks! Storm clouds can block the signals anywhere in the signal path(s). Rain clouds do too ~ even if it's not raining yet. Water-laden clouds make some of the BEST signal attenuators.
So one may have a gorgeous day in San Diego (let's say), but storms back east could trash satellite reception at his location and potentially everywhere else!
As you know, weather conditions all over the US are changing constantly with many severe storms occurring this past week and during any winter. In fact this week there was total signal loss on several satellites and I suspect storms back east were a big factor.
So it could have just been issues of timing for you. The UPLINK had intermittent problems with signal paths semi-crippled by weather... YOUR weather was CLEAR, but your reception was far from problem free ~ only because of weather problems elsewhere.
If you see intermittent satellite reception do check out the weather... especially back east.
Hope this helps!
