Cable installation
Where required, you must use standard shielded Codan cables for the power and control
cabling to ensure safety and EMI/EMC standards are met.
In installations where the cables are not supplied by Codan, all power and control cables
must be assembled in accordance with drawings supplied by Codan.
General guidelines
Use the most direct route possible for the cable runs. Secure the cable runs with cable
ties or other suitable clamps.
You may install the indoor/outdoor interconnecting cables underground (in 75 mm PVC
pipe, for example), or supported by an overhead catenary wire. If the transmit and
receive IF coaxial cables are identical, mark the cables at each end before you install
them. Also, ensure that there is enough slack left to make antenna adjustments without
straining the cables.
Securing cables
Once connections have been made, it is important to secure cables so they do not hang
loosely or flap in the wind.
To ensure water drains off the cables and not onto the connections, create a loop in each
cable that hangs lower than the connectors.
CAUTION
Loose hanging cables tend to elongate over time, causing the conductors
to stretch and the performance of the cables to degrade.
CAUTION
The cables should be secured in such a way that water falling on the
cables does not run directly onto the connections.
