Mounting the base station to a tower
To mount the base station on a tower:
1 Mount a back board or plate to the tower.
This back board or plate is custom hardware supplied by you, the service provider.
Examples of material you may want to use for your back board or plate include a 1/4 inch
aluminum plate, 3/4 inch green-treated plywood, or 2/12 inch green treated lumber.
2 After you have mounted your back board or plate to the tower, mount the base station to
the plate using installation kit 123-0100-0130.
Mounting the base station to a 19 inch rack
Base stations can be mounted to a 19 inch relay rack. Typically, NextNet Wireless stages this
rack for customers as a service.
After staging, the base stations are mounted in the rack and wired to the TVS modules, the
power supply, the backbone switch, and grounding plate.
If you desire to stage your own relay rack, you must use two 19 inch brackets (part number
350-0100-0101) and at least one grounding plate (part number 30-0100-0020).
Grounding the base station
The grounding location differs depending on the type of base station you are using.
• Base stations with the ability to change their modulation method (AMOD base stations)
have a grounding connection on the hinged side of the base station.
• Base stations without the ability to change their modulation method have a grounding
connection at the base of the antenna connection.
To ground either type of base station, run a 6-gauge or higher grounding wire from this
connection to the ground bar on the rack, to the building’s ground connection on the roof, or
to the grounding location at the tower.
The ground of the power can be either negative or positive. The 48 volt power input to the
base station is floating, so either the positive or negative can be grounded.
