External Radio Unit Installation Guide
2
Insert a bolt into one of the three diamond-shaped holes in the mounting
bracket and slide it through the hole on the other side.
3
Slide a washer over the bolt.
4
Twist a hex nut over the bolt and partially tighten it.
NOTE:
Do not fully tighten the hex nut yet. You may need to adjust the
orientation of the pipe.
5
Repeat steps 2 to 4 for the other two holes.
6
Adjust the pipe orientation if necessary, and tighten all three hex nuts.
Under the eaves Position the bracket so that it is at the end of the pipe (as far from the bend
in the pipe as possible). This will maximize the distance between the ERU
and any obstructions, such as the eaves, wall, or roof. Make sure the bend
in the pipe is oriented as shown below.
Rooftop Position the bracket so that it is centered on the long end of the pipe. Make
sure the bend in the pipe is oriented as shown below.
