5.
Connect the dual-coax cable to the power injector dual-coax ports (F-type connectors) on the
bridge.

You should securely tighten the cable connectors (15 to 20 inch-pounds) using a small wrench.
6. Connect the ground wire to the bridge.
7. Align the bridge and tighten the nuts and bolts.
Bridge Brackets
The two bridge brackets mount on the back side of the bridge housing. Each bracket mounts on two
screw posts on opposite ends of the unit. The support pin on the bridge bracket must be facing the side
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 2.
Table 2 Mast Bracket Attachment Methods
