    Default How to fix Ku LNBF for C band Dish


    Hi, I need to add a KU LNBF for my C band Dish, I need to use the C LNBF also, so I can not replace my C LNBF. Other than replacing the C LNBF with a C/KU LNBF can I just add a KU LNBF?

    If so what is the best way to fix the KU LNBF.

    As per some reading I found there are some dual band LNBFs which has KU Lnbf on top of the C. So I have cut the top of the C LNBF and fixed the KU on top of the C Lnbf, but no luck.

    There is another kind too. They put the ku lnbf on the side of the C band lnbf on the same scalar ring. But with compromises. We will loose some signal because of angle differeance. Can you post the photos of your experiments so that we might learn and also might help you to succeed.

    also specify;
    what sats do you want on cband and
    which one on ku, if the same sat then
    you need combined c - ku lnb.
    if seperate sats then you can use c and ku
    lnbs seperately

    Thanks for replys.

    I will post some pictures in few hours time. I do not mind rotating the dish to watch KU channels. So I can fix a KU Lnbf separatly and I already have these separate KU Lnbf with me which I want to make use of.

    Cheers

    You can drill a hole to suit your KU LNB in the scalar ring as close as possible to centre (focal point). A friend of mine has done this and it seems to work quite well.

    Hi,

    Is there a difference in the offset KU lnbf and prime focus Ku Lnbf?

    After so many experiments I managed to fix a offset KU Lnbf for the 6ft prime focus motorised dish, but that was replacing the C Lnbf with the KU one. So I can not watch C band channels.

    I was not successful with the combination. I remeber somewhere I saw somebody cut the rear of the C LNBF and fixed Ku and there were some pictures of the inside view of the LNBFs. Unfortunatly after weeks search I still could not find it.

    Really appreciate any help with regard to this.

    Cheers
