    In the pre Sky & Virgin Media days, there was a time when some people used to have a large dish for satellite TV. I’m guessing they must have been in the 2.5 to 3m range.

    Are they completely obsolete now?

    Anyone tried using them for radio astronomy?

    It is BAA member Robin Leadbeater at the Three Hills Observatory.

    That is my simple  small dish setup using currently used sat TV frequencies. I think the big ones used lower frequencies (C band ?) and I believe are good for making Hydrogen line receivers if you can find one (more popular in the US I think)

    Thanks guys. I’ll take a look.

    It’s not just amateurs using off-the-shelf communications hardware to do radio astronomy, incidentally.

    On a larger scale, I believe the Australian SKA Pathfinder (ASKAP) is built out of standard 12-metre dishes that are used by telecoms companies. Of course, the detectors and mounts needed to be bespoke, though.

    Many  years ago now we had a Society  visit  to the home of John “Radio” Smith, which was near to Rudgwick in West Sussex/  He  had a very large  Ex Radar  Ariel  which was in the  range of 20 to 25ft  size.  This was  guarded by his Bees !!!!!
