[QUOTE="dxsat, post: 532901, member: 193607"] Sound advice, but I would disagree with the point about satellites ageing. They typically lose radiated power over their lifetime, but this is factored into the specification at launch, which could be around 130% of that needed to get predicted coverage on the ground. At the end of life, the satellite has no reserve left but has the same signal strength on the ground as it had at the start. If Astra didn't do this, many people in the UK would have severe reception problems at satellite end of life owing to the fact that minidishes are only just big enough. (And the fact that many Sky 'engineers' do a crap job) Astra has to maintain constant power or the whole direct to home system would fall over. [/QUOTE]
