From inside the trailer feed the connector end of the RF Antenna through the prepared hole
leaving sufficient cable to reach the preferred mounting location inside the trailer.

Loop and secure the excess co-axial cable in the cavity and connect and finger tighten the co-axial
RF connector to the UMD
8.
Cable tie the antenna cable to existing cabling or components that do not get hot near the
firewall hole and up the evaporator cavity.
9.
When connecting the RF antenna cable to the UMD ensure there is sufficient length available so
that there is no tension or kinking applied to the cable at the connection point.
Avoid routing the cables any closer than three inches of pipes, valves (plumbing) or parts of the
engine that become hot during reefer operation.
RF Antenna Installation
–
Physical Location Inside the Trailer:
For optimal results the antenna should be mounted to the roof of the trailer in a horizontal position. Ensure
that the antenna is located out from the back wall as far as possible but where it is still protected from
damage by the internal bulkhead of the fridge unit
–
this provides the best opportunity for the antenna to
communicate consistently with any tags located inside the trailer.
Wherever possible the RF Antenna should be located 300mm away from any steel such as fridge supports,
internal bulk-heads etc
Use P-Clips to tidy up excess cabling and fasten to the internal wall.

Recommended Antenna
The UMD is designed and certified to work with the recommended antenna 2J model 2J6A41BG. Use with any
other antenna could adversely affect the electromagnetic emission characteristics and will violate the terms of
certification and require retesting.
