    Default C/KU LNB on a mesh satellite dish.

    Hi everybody,
    I am just wondering what people think of the reception of the satellite's with a C/KU Universal LNB on a mesh dish. I have always been under the assumption that you need a solid dish to pick-up decent KU reception.
    I notice in another thread Leroy uses a C/KU LNB on I presume a mesh dish. Just wondering what people's experiences are? Thanks.

    It's all compromise. If you prefer cband, take that feed, if you prefer KU, use that. Using a combined feed compromises your capacity to chase that elusive hard to reconcile low strength transponder.

    I use a 2.3m mesh and I'm reasonable happy with the results. I can't use it with the optus sats due to their 'skew if' skew though!

    Wink Solid versus Mesh Dishes.

    Let's lay this speculation to rest once and for all.
    The Wavelength Metres for a given Frequency equals Speed of light / Frequency in MHz.
    All Antennae designs revolve around this fundamental Fact.
    Short form is 300/ Fo MHz x 100 = mm.
    For Ku, 300 / 12500 x 100 = 2.4 mm.

    For C Band, 300 / 4000 x 100 = 7.5 mm

    Any mesh greater than a half wavelength becomes progressively inefficient.


    Regardless of any ad hoc anecdotal claims, them's the cold hard facts as confirmed on Antennae Ranges.
