Here we take a look at some vintage 1980 s satellite receivers and a BSB square dish , the BSB system had a very short life which was not surprising as it only had 5 channels compared to the Astra / sky systems that had 19 channels , due to the passing of time I cant remember significant dates but I am sure a google search will give you more information , these are more than 30 years old now so I don't think you will see too many still around, and I cant even begin to think how many of the Tatung early bird boxes I have binned over the years.
