Antennas and antenna cabling
Antenna requirements
Each connectorized ODU requires one external antenna (normally dual-polar). These antennas are not
supplied by Cambium Networks.
Note
To determine when to install connectorized units and to calculate their impact on link performance
and regulatory limits, see
RF cable and connectors
RF cable of generic type LMR-400 is required for connecting the ODU to the antenna. N-type male connectors
are required for connecting the RF cables to the connectorized ODU. Two connectors are required per ODU.
Use weatherproof connectors, preferably ones that are supplied with adhesive lined heat shrink sleeves that
are fitted over the interface between the cable and connector. Order CNT-400 RF cable and N-type male
connectors from Cambium Networks

Note
To select the correct connectors for the antenna end of the RF cable, refer to the antenna
manufacturer's instructions.
Antenna accessories
Connectorized ODUs requires the following additional components:
•
Self-amalgamating and PVC tape: Order these items to weatherproof the RF connectors.
•
Lightning arrestors: When the connectorized ODU is mounted indoors, lightning arrestors are required for
protecting the antenna RF cables at building entry. One arrestor is required per antenna cable. One
example of a compatible lightning arrestor is the Polyphaser LSXL-ME or LSXL (not supplied by Cambium
Networks).
