[QUOTE="Channel Hopper, post: 10880, member: 175144"] [B]Sky's signal shits trougth the day [/B] Classic ! I dont believe that the Sky signal will be variable through simply one cause Reception loss will be made up of the following (in order of magnitude) 1) Dish size - proven by the article 2) Atmospherics, actually the thermal noise generated around the reception equipment , which will swamp the signal with unwanted interference, and cause the receiver hardship to identify the real channel information. The LNB will bake in the sun if the dish is of solid type, especially if its white 3) Receiver sensitivity, linked with 1), however again the temperature of the unit during daytime operation will cause a difference in recption characteristics unless kept stable with a fridge unit 4) Satellite transponder power deviation, Sky/Astra/Eutelsat can turn down the signal as and when required, this may be down to the programme content (affecting individual channels), territorial license agreements (complete transponder for movie PPV), and satellite power fluctuations (complete bird) 5) - Pointing errors, in a hot country the dish components - mainly the reflector, will distort as a result of the heat, altering the gain by changing focus, however the post, elevation and maybe alignment will change because of the different expansion rates 6) Local effects - beach towels hanging out in front to dry, swarms of flies, plagues of locusts, etc etc [/QUOTE]
