With the monoblock LNB, the dish is pointed at Astra 19 East and the 2nd side of the LNB tilted upwards to get Hotbird 13 East,?, I have got a 80cm dish with a dual output monoblock LNB in my shed waiting to be re-fitted,
He is not talking about Astra 1 at 19.2 here - he requires Astra 2 at 28E (read his posts) and I am fairly certain you will not get a monoblock to cover 15 degree separation. He needs two separate lnbs on a dish centred on 19.2 with the two lnbs either side - but then he may as well add a third lnb for 19.2. It is possible on a 60cm dish in the South of the UK but an 80cm woukd give better 'rain fade' for bad weather.
As regards connecting receiver(s) to it - it depends on what he wants on them - if he wants a full 7 day EPG on 28E then a freesat box would be ideal for that To the OP what receiver do you have at present?
Well if none of your local fitters know about Hotbird I would look further afield for someone else. Because they are unlikely to know about fitting 2 LNBs on one dish either.
If it was me I would realign the Astra 2 dish and fit another for Hotbird, 60cm should be enough. Get a cheap fta receiver and a diseqc switch.
Never mind - I bought a tm5402. Then I can either buy a diseqc switch, or just use the sky box for the Astra channels and take advantage of the better epg. Cheers
