    Question C-Band LNBF with Ku-Band Offset Dish ?

    Dear Friends
    A basic doubt.

    Can we attach an additional C-Band LNBF to a Ku-Band offset solid dish ?
    If yes how ?

    Thanx

    It can be done, but signal strengths will be suspect, as your off-set dish is no where near the size required for C-band reception, also if your using an off-set dish for C-band, you really do require a off-set scalar ring, which is cut on the taper to suit the dish serface, as a Ku feedhorn is.
    But simply attaching a C-band LNB along side the Ku one might get you a signal, it's all trial and error, simply hold the LNB while watching a signal strength indecater , and see if you can pick up a signal.

    as above is correct plus the dish should have been originally offset for c band, to allow the c band size acceptance.
    try it out, it will be an experience.
    the lnbs should somehow be on a horizontal line along the set focal length, with the angles now to set for the particular sat.i have worked on 3 lnbs for ku but not c band on offset, because i had a 90cm dish which couldnt receive c band.
