We have an old-ish (dating from a year or two after the start of digital) Sky dish fitted with an LNB, which we resurrected last year for a none Sky digital box use. I am now finding reception fails after a few minutes watching a certain channel (BBC 1 and perhaps others less watched). I'm fairly sure the box is OK, the alignment OK and the cabling is OK, but think it may be the LNB - so I'm looking to replace it.
All they seem to sell is quad LNB's, but I only need one output at the moment. Can I just connect to one output and seal up the others?
