Found some info on another web forum in Ireland here.
One of the regulars has put together a Gibertini cassegrain dish (60 cm) and a Wild Blue Ka lnb, and is receiving the RTE test very clearly from KA-SAT.
I looked up Wild blue dealers and both lhcp and rhcp refurb lnbs are availabe, the latter useful for torroidal / Fibo owners.
In the US though, and expensive, $150 plus shipping of $192 for a refurb
Anyway, any enthusiasts who just can't wait......
All credit to Apogee, who assembled and tested this set up and then posted all the info online.
