    RG174 Coaxial Cable

    Stock Code: RG174U

    Carries a 50 Ω coaxial line through tight spaces.
    A thin, flexible 50 Ω coaxial cable with a 2.80 mm outer diameter. A 7/34 AWG stranded copper inner conductor and an 88 % tinned copper braid carry the signal inside a black PVC jacket.

    Key features
    0.48mm
    Inner conductor diameter
    The 7/34 AWG stranded copper wire leaves the cable room to bend.
    1.52mm
    Dielectric diameter
    Solid polyethylene insulation holds the spacing between conductor and shield.
    88%
    Braid coverage
    A 38 AWG tinned copper braid wraps the inner conductor.
    2.80mm
    Outer diameter
    The black PVC jacket finishes the cable thin enough for tight ducts.
    101.0nF/km
    Nominal capacitance
    Long line calculations use this nominal figure.
    28.0mm
    Minimum bend radius
    The cable stays above this radius during installation.
    EVERYDAY USE
    Works in tight spacesThe thin jacket and small bend radius allow winding runs inside ducts and equipment.
    Attenuation shifts with temperatureAttenuation climbs with rising temperature and falls as it drops, so link budgets in hot areas account for the change.
    Tinned copper braidThe braid shield separates the line from outside interference and protects the inner conductor.
    Attenuation figures are nominal and change with temperature, rising 0.18 % per °C.
