RG11/U Foam  / Belden  7731A Coaxial Cable

RG-11/U type,

14 AWG solid .064" bare copper conductor,

Gas-injected foam HDPE insulation,

Duofoil® + tinned copper braid shield (95% coverage),

PVC jacket.

 

If you are building a four square on the low bands (40/80/160) then this 75 Ohm RG11/U type cable is ideal for the phasing runs from the switching box to the individual antennas. It is foam filled so has a 85% velocity factor meaning it will reach from the antenna to the array switching box in a standard 1/4 wave length. A 1/4 wave of standard RG11/U with its lower velocity factor will be too short to reach.

Available cut to order in any length up to 305 metres. We can cut and measure for you to the nearest 1cm it you want a pre-cut set.
