    Hi All

    I've got a quad LNB that I'm planning to place on my Sky dish, replacing the single unit on it.

    Is this a straightforward DIY swap or are there any gotchas I need to be aware of?

    Thanks

    Peter

    You might want to put some rubber boots on the outputs to keep moisture out. I didn't, and... it didn't seem to matter. As Tony says, very straightforward.

    I just paid €27 odd for mine plus €48 for 100M of cable, from a reputable Irish supplier ;).

    Totalled €118 when VAT and carriage included.You might get away with less cable depending on your set-up. I have a fairly long run from my dish to my equipment rack.

    No. If you want to know why, you should read a bit more:

    as loing as you have the dish aligned right, you should get equal signals along all 2/4 outputs.

    @ the LNB, I got an installer to do it.

    Maybe my dish was just too old, and gone rigid or something but I couldn't manage to release it.

    In a nutshell, satellite is totally different to cable and aerial so don't expect the same rules to apply.
