Chapter 3 Mounting and Alignment Overview
Bridge LEDs
Bridge Bracket
The bridge bracket mounts on the back side of the bridge housing. The bracket mounts on four screw
posts on the unit. The support pins on the bridge bracket must be facing the sides of the unit. These
support pins are used to suspend the bridge in the notches on the mast mounting bracket until you secure
the mounting bolts.
The bridge brackets must be positioned to obtain the correct antenna polarization that matches the
remote antenna. The bridge housing contains an antenna polarization mark consisting of an arrow on the
side of the housing. When the bridge is positioned so that the arrow is pointing up, the bridge antenna is
vertically polarized. For horizontal polarization, the arrow should be pointing from left to right. All
bridges must use the same antenna polarization for best operation.
Mast Bracket
The mast bracket attaches to a mast or tower support and is used to secure the bridge.The procedure for
attaching the mounting bracket to the support depends on the pipe diameter, as shown in Table 3-1.
Note The U-bolts supplied with the bridge support mast diameters up to 1.75 in. (44.5 mm). For larger masts,
you must supply the U-bolts to attach the bridge.
Bridge LEDs
When you power up the bridge for the first time, it starts in a special installation mode. The LEDs
indicate the startup status, operating mode, association status, and received signal strength. This
information simplifies the process of activating the link and positioning the antenna from the bridge
mounting location.
Table 3-1 Mast Bracket Attachment Methods
Mast Type Mast Diameter Mast Attachment Method
Roof mount,
small mast, or
tower
1.5 to 2.5 in.
(30.5 to 63.5 mm)
Attach the pipe inside the mounting bracket, between the
bracket and bridge.
Large mast 2.5 to 4.5 in.
(63.5 to115 mm)
Attach the pipe outside the mounting bracket, away from
the bridge.
