40mm C-band LNB for Laminas 120

1st Official Post

    Hi,

    I got a new brand Laminas 120 with Inverto Premium 0,2dB LNB, but now I'm looking for a C-band LNB to discover this new world. I need a 40mm neck LNB. Anyone can suggest me a good model ?

    Thank you so much

    As on sats uk, 40mm is below waveguide cut-off at C band so I don't think there will be any.

    Frage mal bei Laminas an, ob es für die 120er auch einen Feedarm mit 65 mm Aufnahme gibt.

    Ask Laminas if there is a feed arm with a 65 mm mount for the 120s available.

    If you don't specify the antenna size and the approximate location, posting is useless if it's about signal acquisition.

    "Auto" should never be in the settings.
