Installing the
Broadband Global Area Network (BGAN)
Fixed Mount Kit
Product description – BGAN fixed mount kit
Although the BGAN satellite modem terminal is designed for portable use, the BGAN Fixed Mount Kit
(HNS part number 3004066-001) allows you to permanently mount the terminal if this option is desired.
The fixed mount kit (Figure 1) consists primarily of a tubular pole mount assembly with mounting brackets
on each end. The base bracket attaches to the roof or other structure, and the terminal bracket attaches to
the BGAN terminal. Power and network cables are also included.
This document describes how to install the BGAN Fixed Mount Kit. It references the BGAN Terminal
User Guide, HNS 3004077-0001, which is provided in PDF format with the terminal on a compact disc
(CD).
Step A. Inspecting the parts
Make sure you have all parts listed on the shipment box before beginning the installation; you should have
following parts:
1. Fixed Mount assembly
2. Tamper-proof hardware
3. Bits and tool to install tamper-proof hardware
4. 30 m Extension Power Cable
5. Grounding Cable
6. 2-30 m Ethernet/ISDN Cable
7. Level indicator
8. Compass
9. This instruction sheet, HNS 3004090-0001
The fasteners for securing the base bracket to the structure are not provided as part of the mounting kit.
Step B. Using tamper-proof fasteners
You can use the standard fastener hardware provided on the pole
brackets or, for improved security of the installation, you can
replace the standard fasteners with the provided tamper proof
fasteners (Table 1).
To replace the standard fasteners with the tamper-proof fasteners
(Table 1) refer to Figure 2 for the terminal bracket and Figure 3
for the base bracket.

Step C. Determining where to install the terminal
In order for your terminal to work correctly, it must be installed in a location that provides a clear,
unobstructed, line of sight between the terminal and the satellite. Any objects such as building structures or
trees may degrade the quality of the satellite to terminal connection. To determine where to install the fixed
mount and terminal, you need to determine that you have both a clear unobstructed line of sight to the
satellite and that your fixed mount is aimed in the approximate direction to the satellite. A graphic example
is provided for you at Figure 4 and a full size worksheet for your use is provide at Figure 10 (page 7). An
example of directional aiming is provided below

Figure 4 - Inmarsat BGAN coverage map
To determine the direction from your location to the satellite, i.e., directional aiming, follow the steps 1-4
(below).
1. Refer to the Inmarsat BGAN coverage map at Figure 4.
2. Find your geographical location on the map. In our example, the mount installer is located in Miami,
Florida, USA.
3. Determine which satellite footprint you are under. Draw a line from your location to the image of the
satellite (in the same satellite footprint). The compass direction of your location-to-satellite line
determines the gross orientation of the mount. In our example, the mount installer has drawn a line
from the Miami location to the satellite. Using a protractor to measure the line direction in degrees, the
installer determines that the direction is 135 degrees.
4. Using the full size map (Figure 10, page 7), you may now draw on the map to determine your locationto-satellite direction.
5. Using the compass (provided), align the mount so that it points in the same compass direction that you
determined in step 3, above. If the line of sight is clear, i.e., no obstructions, then you may use the
location to attach the now aligned mount to the structure.
