Antennas Located on Top Rail
GPS and GSM Antennas:
RF Antenna:
The RF antenna
should be mounted inside the refrigerated trailer (the “box”) for optimal results when
receiving data from RF temperature or door tags located within the trailer. If the customer configuration is for
fridge interface only with NO internal RF Tags then the Antenna is not required.
Internal RF Antenna:
1.
Drill a small pilot hole through the firewall and ensure the loom and hardware clearance from the
engine bay side is adequate.
2.
If OK, enlarge the hole to 20mm and remove any drill swarf from both sides of the firewall
3.
Feed the cable into split tubing up to 150mm from the connectors at each end of the cable
4.
Feed the mounting plate onto the RF Antenna Cable and tighten into place using the supplied
lock-nut.
5.
Feed the length of antenna cable into 20mm convoluted tubing for protection
