Yes you can BBN, with certain provisos. Firstly the standard 43cm minidish is not big enough forthe reception of many satellites, it should however be OK for Astra 19.2E, there is of course no analogue broadcasting on Astra 28.2E.
If its an older analogue receiver, you may be limited as to the type of LNB it can be set up for. The minidish has a universal, with Local Oscillators of 9.750Ghz and 10.600Ghz and some older receivers can only be set to 10.000 Ghz. If its one of the newer ones it should be set to 9.750 and will operate successfully on the lower band where most of the Astra analogue channels are.
