[QUOTE="brother9, post: 1114557, member: 411346"] Thank you, A33. Good presentation. I did similar calculations earlier: That 1h 9.6m the satellite is in the umbra, more hours in the penumbra (Latin for half-shadow). With the Earth's tilt of 23.5° that umbral cone will indeed be below the satellites on 21 June. They will still be in the penumbra. IF (if !) this sunshine effect on the satellite signals is true, then it should be easily found in the (online) litterature. I have not found such, And there are too many variables: Frequency, Symbol Rate, signal power, signal direction (footprint), LNB temperature, weather at dish, humidity, ionospheric conditions, etc. [/QUOTE]
