to the base station, use 5/16 inch x 18 inch UNC thread bolts and a lock
washer. Use your own bolts to then attach the bracket to the surface.
Mounting the base station to a tower
Use the tower connecting plate to attach the base station to a tower. To mount the
base station on a tower:
1 Find a place on the tower that is suited to base station installation.
a Plan to install the base station vertically, so the antenna connector is at the
top (facing skyward), and the other circular connectors are at the bottom
(facing the ground).
b Make sure the area above and below the location where you want to install
the base station has a good distance for clearance. This clearance allows for
proper air circulation and heat flow from the heat sink fins on the back of the
base station and for cable connections.
2 If you are installing the base station to a tower, you must use mounting plates.
Attach the plates to the base station, then attach the mounting plates to the
tower according to the directions from the plate manufacturer.
Connecting the antenna to the base station
This section provides tips you can use to connect the antenna to the base station. It
also provides step-by-step instructions for connecting the components to each
other.
Antenna connection tips
Use the following tips when connecting the base station to the antenna:
• You connect the antenna to the base station using a coaxial cable. The size of
the cable depends on the distance between the base station and the antenna.
• The greater the distance, the larger your coaxial cable needs to be, in order to
maintain low signal loss.
• It is recommended that you keep signal loss to a minimum. At a maximum,
the signal loss should be no more than 2 to 3 dB, including all coaxial cable
and connectors.
• Use short coaxial jumpers from the base station to the main coaxial line, and
from the main coaxial line to the antenna. It is recommended you use 1/2 inch
