Antenna Assembly
It is recommended that antennas be assembled prior to transportation to the Mote site. Assembly
includes the fitting of lightning arrestors and coaxial cables. Cover the free end of the coaxial cables
with tape to keep out dirt until installation.
Yagi Antennas
1.
Carefully remove the antennas from their cardboard boxes.
2.
Note the orientation on the antenna as there is an ‘UP’ marking.
3.
Slide the antenna clamp over the end of the antenna and fit the two nuts and bolts.
4.
Position the two “U” clamps into the bracket so they are parallel with the antenna boom.
Note: If the antennas are assembled before transportation to the Mote site, the following steps are
to be done once at the site.
1.
Slide the antenna bracket onto the mast, 6” from the top. Align the antenna elements so they
are vertical (parallel to the mast), and tighten the clamp and ‘U’ clamp nuts.
2.
If you are using two Yagi antennas, repeat step one for the second antenna but position it
below the first antenna. Typically, the antennas will be positioned 90-120° apart.

Omni-directional Antennas
1.
Carefully unpack the antenna.
2.
Fit the cross-arm bracket to the antenna mast and tighten.
3.
At the end of the cross-arm, assemble and fit the antenna mounting bracket near the end of
the cross-arm.
