To mount and connect an external antenna to the connectorized ODU, proceed as follows:
1 Mount the antenna(s) according to manufacturer’s instructions.
2 Connect the ODU A and B interfaces to the antenna(s) with RF cable of type
LMR-400 (Cambium part numbers 30010194001 and 30010195001) and N type
connectors (Cambium part number 09010091001). Tighten the N type connectors to
a torque setting of 1.7 Nm (1.3 lb ft).
3 If the ODU is mounted indoors, install lightning arrestors at the building entry point:
4 Form drip loops near the lower ends of the antenna cables. These ensure that water is
not channeled towards the connectors.
5 If the ODU is mounted outdoors, weatherproof the N type connectors (when antenna
alignment is complete) using PVC tape and self-amalgamating rubber tape.
6 Weatherproof the antenna connectors in the same way (unless the antenna
manufacturer specifies a different method).
