Installing external antennas to a connectorized
ODU
PMP 450i Series
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.
