Attaching and weatherproofing an N type connector
The following procedure should be used to weatherproof the N type connectors fitted to the
connectorized ODU (AP/SM/BH) and antenna. This procedure must be followed to ensure that there is
no moisture ingress at the radio ports. Failure to properly seal N-type antenna connectors can result in
poor link performance or complete loss of radio communication.
Use this procedure to weatherproof the N type connectors fitted to the connectorized ODU and
external antenna (if recommended by the antenna manufacturer).
1
Ensure the connection is tight. A torque wrench should be used if available:
2
Wrap the connection with a layer of 19 mm (0.75 inch) PVC tape, starting 25 mm (1 inch) below
the connector body. Overlap the tape to half-width and extend the wrapping to the body of the
LPU. Avoid making creases or wrinkles:
Note
Cambium recommends assembling the antenna, attach the ODU and cabling, and to
seal the RF connections before installing the unit at the deployment site.
Note
N type connectors should be tightened using a torque wrench, set to 15 lb in or 1.7
Nm. If a torque wrench is not available, N type connectors may be finger tightened.
