8. Connect the end of the Receive antenna cable to the CBS, then
attach the Receive antenna pigtail to a Receive Antenna Cable.
Connect the other end of the Receive antenna cable to the CBS.
Note: Protect the RX antenna BNC cable connector from the freezer
environment.
• Water condensation inside and dripping water from outside an
unprotected BNC connector will trigger electrolytic corrosion
that will eventually destroy the connector.
• Carefully choose freezer RX antenna locations so that the inline
BNC cable connectors are in a room temperature environment
outside the freezer wall.
• For conventional stand-alone freezers, use the 7730-K050-V003
"Kit - Rx Antenna w/18m cable" or 7730-K054-V003 "Kit - Rx
Antenna w/15m Cable (for 100mW CBS)." These antennas
have a 25cm (10inch) antenna lead.
•
For large walk-in and oversized freezers with high ceilings, use
the new long-lead 7730-K055-V002 "Kit - Rx antenna (6m lead)
and 12m cable." These antennas have an extended 6m (20ft)
antenna lead for better freezer routing, but they must be used
with the corresponding shortened 12m (39ft) antenna cable for
proper operation.
• In special situations, it is possible to seal the inline BNC
connector from the freezer environment. See the detailed
instructions below.
9. Use cable ties to secure the antenna cable.
10. Seal all cable entry holes with permagum sealing compound.
• Unsealed holes will cause icicles around entry holes and frost
buildup on nearby product. If the inline BNC connector is not
protected, condensation will drip down the antenna cable and
trigger electrolytic corrosion inside the connector that will
quickly destroy it.
