Viewing more TV from other satellites covering Europe
You are not limited to the UK satellite constellation. There are many other channels available on other satellites such as Astra 19, Hotbird 13 or Arabsat 26. Many of these are available for free, but they may have limited availability of English soundtracks. For example you can watch Eurosport for free on Astra 19, but it is the German Eurosport with no English audio!
The best setup for a multisatellite system is to install a motorised dish. The motor will move the dish to the correct satellite depending on what channel you select on the receiver.
Many channels on the UK satellites, Arabsat, Astra1 and Hotbird can easily be received on an 80cm dish on a motor. And with the latest motors you can ensure that your dish moves between the satellites quick and swift.
