5G vs. C-band

  • Hello,


    I would like to open this topic to share experiences and tips for 5G and C-band interference.

    In Hungary 5G network installation has been started below 3.8 GHz.

    Some DX-er reported near 5G tower (around 5km) C-band almost totaly died. Over 3.8GHz as well.

    So if somebody has some similar experience or solution, please share in this topic.:3:

    Location: Hatvan/Hungary
    C band: dyras 175cm (83E-34W), Kaonsat 13K LNB
    Jonsa 240cm PFA (40.5W), Kaonsat 13K LNB
    KU band: 120cm offset+Invero BU single LNB
    Receivers: VU+zero 4K, Ustym 4K pro



  • here from me below 3600 ghz no signal, here is the wimax covering the C band

  • Sky and star watchers have gone far from urban areas due to light pollution, I guess the same is expected of C band fans due to the 5G network :88:

  • The ADE antenna helped me against interference in the C band.

    and ADE antenna, spectrum almost without interference.

  • What's an ADE antenna?

    ADE = Axis-Displaced Dual-Reflector Antenna


    It is an antenna with a secondary reflector, similar to a cassegrein or gregorian. The difference is in the picture. These are high efficiency antennas.
