Surge Suppressors
Overview Surge protection is available for coaxial network trunks that span between buildings
and are exposed to lightning. The recommended product has internal gas discharge
surge protectors that absorb very high currents induced into the cable system by
near-lightning strikes. The device indicated has insertion loss of less than 0.3 dB at
the network operating frequency. The unused drop ports must be terminated with a
Modicon 52-0402-000 Port Terminator. If desired, shrink tubing may be used to seal
the F connections.
The device should be accessible for maintenance, and be protected from the
elements if installed outside. The threaded stud should be connected to building
ground.
The recommended product is Relcom Inc. Part Number CBT-22300G.
