User Manual Part 2

Installation 6-6MTX5000 User and Technical Manual
The MTX5000 system may be ordered with Triax, Type “N”, or
TNC cable connectors. Existing installations may use Triax,
Type “N”, or TNC cabling. ‘
Special Note - Triax Installations Over time, flexing and
vibration can cause the connections inside the Triax connector to
deteriorate, leading to high resistance in the DC circuit paths.
This, in turn, can cause erratic and intermittent problems with the
MTX5000 system.
MRC recommends you avoid this possibility by performing the
following:
• Install the Triax connector carefully, following the steps in
“Installing Triax Connectors” on page A-1.
• Support the Triax cable so that any movement of the
cable does not apply stress to the Triax connector.
