    Key features
    3.30kW
    Power handled at the low band
    Average power is 3.30 kW at 30 MHz and drops as the frequency climbs.
    2.30dB
    Loss across the low band
    At 30 MHz the loss over 100 meters is 2.30 dB, climbing to 12.80 dB at 900 MHz.
    2.77mm
    Copper-clad aluminum inner conductor
    The inner conductor is 2.77 mm copper-clad aluminum wire and shows 4.6 Ω/km at 20°C.
    8.05mm
    Two-layer shielding
    A 90% tinned copper braid sits over the sealed APA tape and closes at 8.05 mm.
    6000MHz
    Top of the operating band
    The operating band starts at 30 MHz and reaches up to 6000 MHz.
    25.40mm
    Pulling through tight bends
    The minimum bend radius is 25.40 mm, and the cable should not go tighter than that in duct turns.
    Out in the field
    Polyethylene outer jacketThe black polyethylene jacket closes the cable from the outside.
    Foam dielectricThe foam polyethylene dielectric holds the inner conductor centered.
    Sealed APA tapeThe tape and braid layers stack over one another in a single body.
