UNDER DEVELOPMENT
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 to the antenna(s) with cables of type LMR100, LMR200, LMR300, LMR400
or LMR600. Connect the ODU “V” interface to the vertical polarization antenna and connect
the ODU “H” interface to the horizontal polarization antenna. Tighten the N type connectors
using a torque wrench set to 15 lb in or 1.7 Nm.
3 If the ODU is to be mounted indoors, install lightning arrestors at the building entry point.
Connect the lighting arrestors to the master ground bar of the building:
4 When dressing the antenna cables, form drip loops near the lower ends. These ensure that
water is not constantly channeled towards the connectors.
5 If the ODU is mounted outdoors, weatherproof the N type connectors in this sequence:
•
A layer of 19 mm (0.75 inch) PVC tape.
•
A layer of self-amalgamating rubber tape.
•
A layer of 50 mm (2 inch) PVC tape.
•
Four layers of 19 mm (0.75 inch) PVC tape.
