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 (
Table
46
).

Antenna accessories
Connectorized ODUs require the following additional components:
Cable grounding kits: Order one cable grounding kit for each grounding point on the antenna
cables. Refer to
Lightning protection unit (LPU) and grounding kit
on
2-34
Self-amalgamating and PVC tape: Order these items to weatherproof the RF connectors
Lightning arrestors: When the connectorized ODU is mounted indoors, lightning arrestors (not
LPUs) 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).
