Chapter 5: Installation Install external antennas
Install external antennas
To mount and connect an external antenna, proceed as follows:
1
M
ount 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 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 connector
s.
5
If the ODU is mounted outdoors, wea
therproof 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).
