14.3  Routing the Cable 

After connecting the cable to the ODU it can be routed and secured using standard cable 

routing and securing techniques. When the cable is in place it can then be cut to the desired 

length.  

14.4  Fitting a Surge Arrestor 

If you have opted to fit a Surge Arrestor, it should be installed as described in Section A1.5 

“Lightning Protection”

Cable 

Termination 

The two channels can be separated by means of a patch panel which may include Baluns for 

transmission over 75 Ohm co-axial unbalanced lines. Such equipment should conform to the 

requirements of C.C.I.T.T. G703. An example of a Balun is shown below. It allows the 

transmit and receive data carried over a 75 Ohm cable to be converted to a balanced form for 

transmission over a 120 Ohm signal balanced twisted pair.
