  RG8
       
           (Or "thicknet" - "thick
          {Ethernet}") The original "full spec" cable, used for
          {10base5} {Ethernet} networks.  RG8 is stiff, large diameter
          {coaxial} cable with an {impedance} of 50 ohms, a member of


          the "Radio Guide" series.  The outer sheath is usually yellow,
          to indicate double shielding, so it is often just called
          "yellow cable".
       
          10base5 cable is designed to allow transceivers to be added
          while existing connections are live.  This is achieved using a
          "vampire tap" - a device which (with sufficient practise)
          clamps onto the cable, forcing a spike through the outer
          shielding to contact the inner conductor while other spikes
          bite into the outer conductor.  This is often built into the
          transceiver and a more flexible multi-wire cable carries the
          connection between the transceiver and the {node}.
       
          {RG58} is a cheaper, more flexible alternative.
