Install External Antennas For A Connectorized Odu - Cambium Networks PTP 650 Series User Manual

Chapter 5: Installation

Install external antennas for a connectorized ODU

1 Mount the antenna(s) according to manufacturer's instructions. When using separate antennas
to achieve spatial diversity, mount one with Horizontal polarization and the other with Vertical
polarization.
2 Connect the ODU V and H interfaces to the antenna(s) with RF cable of type CNT-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).
