I have an 88cm motorised dish but have found that I am missing many lower power feeds in the SE UK.
So I have set up a 1.2m dish with a prime focus of 10 East and a second LNB on 7 East. This seems to be working well.
Surprising there seems to be little information on the losses of an off-prime focus LNB for orbital separation.
The only factual reference I have found is Multiple Satellite Feed Systems – SSE who quote a 1db loss...
Multi-lnb losses off prime focus
