Installation Notes
Mounting the Antenna
A mounting kit is provided with the antenna. This kit enables you to mount the antenna to masts up to
2.5 in. (6.3 cm) in diameter. The antenna can be vertically or horizontally polarized, but it must be
mounted so that the parabola is in the vertical plane.

mounted so that the parabola is in the vertical plane.
Note
To meet regulatory restrictions, the external antenna model of the bridge and its external antenna must
be professionally installed.

Note
To ensure correct installation and grounding, install the antenna in compliance with your local and
national electrical codes: National Fire Protection Association (NFPA) 70, National Electrical Code
(U.S.); Canadian Electrical Code, Part 1, CSA22.1 (Canada); and if local or are not available, refer to
IEC 364, Part 1 through Part 7 (other countries).

Adjusting Polarization
A decal is attached to the star mounting plate indicating how the antenna should be mounted for vertical
polarization. To obtain vertical polarization, mount the antenna so that the arrow on the decal is pointing
up. To obtain horizontal polarization, rotate the antenna clockwise 90 degrees so that arrow on the decal
is pointing to the right (at the 3 o’clock position).

Note
The antennas of any two units that are intended to form a link and associate with one another must be
set for the same polarization.

Mounting the Antenna to a Mast
Follow these steps to mount the antenna to a mast.
Step 1
Remove the four #10 cap screws, lock washers, and flat washers from the mounting kit’s hardware bag.
Step 2
Position the feed tube as shown in Figure 1, aligning the polarization pin on the feed tube with the hole
in the dish.

Step 3
Insert cable through the hole and install screws with a 5/32-in. (4-mm) long shank hex key and tighten.
Be sure to install the lock and flat washers. Do not overtighten.

Step 6
Determine the antenna polarization for your installation and position the antenna appropriately:
a.
Vertical: the arrow on the decal is pointing up.
b.
Horizontal: the arrow on the decal is pointing to the right (at the 3 o’clock position).
