Side View of ODU Mounted to a Mast (Pointing Down)
Attaching the Mount on the Mast
This section illustrates installation on a vertical mast. A horizontal support is also perfectly acceptable.
1. Cut the length of rubber collar material (using a sharp knife) so that it wraps around your mast with a
small
gap (.10 - .25 inch) between the ends
.
2. Select the proper size hose clamp and install the rubber collar securely on the mast. This collar is used to
hold the weight of the Outdoor Unit during installation and antenna alignment.
3. The bolts and hardware supplied will accommodate masts from 1.9 to 3.5 inches in outside diameter.
4. Use
a
safety rope or
second person
to hold the ODU in position on the mast, resting on the rubber collar.
Install the top clamping yoke first. Install the bottom yoke last.
Note
: Be careful not to drop the ODU. The weather seals protecting the antenna and microwave transceiver can be
damaged.
Visually aim the antenna as precisely as possible in azimuth and elevation (i.e., both horizontally and
vertically).
Use a map and compass to set the correct direction. Tighten both yokes and elevation arms securely
until ready for antenna aiming.
