Chapter 2: System hardware
Antennas and antenna cabling
Antenna requirements
Each connectorized ODU requires one external antenna (normally dual-polar), or if spatial diversity
is required, each ODU requires two antennas. These antennas are not supplied by Cambium
Networks.
For connectorized units operating in the USA or Canada 5.4 GHz or 5.8 GHz bands, choose external
antennas from those listed in
antennas. For links in other countries, the listed antennas are advisory, not mandatory.
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 type CNT-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 RF cable and N type male connectors from Cambium Networks
