STANDARD CABLE CONNECTIONS
In addition to the DC power connection, an optional ignition sense
connection must be made, or it will not work properly. This is done
using the three-wire power cable. In the case of a vehicle installation,
the power source is typically the vehicle battery. Cables should be
routed appropriately, and cable ties and clamps should be used as
required to ensure that vibration and/or rubbing of the cables does not
occur.
POWER CABLE ASSEMBLY
A 6m power cable with a +12V power line and a +12V ignition sense
line is included with the Transceiver Unit. The fuse is a standard 7.5A
automotive mini blade fuse.
NOTE: To protect against the risk of fire, always replace fuses with
the same type and rating.

IGNITION SENSE (ORANGE WIRE)
Route and connect the orange wire (ignition Sense) to a switched
12 VDC source, such as ignition switch or fuse block. Extend use of
ignition sense in accessory position (ACC) by the end user may lead to a
discharged car battery.
NOTE: Ensure that the connection is switched to source-OFF when
ignition is off or in start and ON only when ignition switch is in
ACCESSORIES or RUN position.

Installing the TU - Fixed and Mobile
BASIC INSTALLATION PROCEDURE
While the installation of the MSATe mobile satellite radio is
straightforward, it is essential that the installation be done correctly. The
basic installation procedure is as follows:
I. Decide where you are going to install the antenna, TU, and handset.
II. Ensure that the TU is located inside the vehicle or a building and that
it is attached to something structurally sound. Loose mounts that
vibrate will degrade performance.
III. Determine the cabling required for the installation of each
component.
IV. Perform the installation of the antenna, TU, and handset.
V. Connect the antenna and the handset to the TU.
VI. Connect the power to the TU.
VII. Power up and commission the radio.
GENERAL INSTALLATION
• For ease of service, route the radio cables and power cables
together.
• Always disconnect the negative side of the vehicle battery prior to
any electrical work.
• Whenever routing cable through holes drilled in metal or through
bulkheads, use grommets and RTV sealant to weatherproof all
holes drilled on the outside of the vehicle.
• Use cable ties every 30 – 45 cm (12-18”).
• The TU can be mounted in either the horizontal or vertical position.
• The main power line should be connected directly to the vehicle
battery (or 12 VDC power supply). If you must connect it to another
circuit, ensure sufficient amperage is available. In the case of a
fixed-site installation, tie the Battery and Ignition Sense wires
together on the 12 VDC power source.
• The ground line should be connected directly to the vehicle’s
battery ground.
• Install the TU in a protected but ventilated area (inside building
or vehicle). Allow at least one (1) inch space around all surfaces,
except for the surface attached to the mounting bracket to
provide adequate cooling. Ensure that the location is accessible for

13 LIGADO NETWORKS MSATeINSTALLATION GUIDE
servicing.
• The TU is not waterproof.
• Always provision the wiring into the TU with a drip loop.
• With the exception of the TU to Antenna cable, do not route the
cables outs.
TU Mounting Bracket Information
NOTE: Use care when drilling through the body of a vehicle to avoid
puncturing critical items.
The bracket is connected to the TU with two (2) provided screws. There is
a 5mm gap between the TU and the bracket.
Instructions for the installer:
• The mounting bracket should be used for mounting the TU.
• Mount the mounting bracket onto a flat surface using at least four
(4) screws (not supplied). Use screws with diameter between 3 to 4.5
mm. Vibration resistant screws or lock washers should be used.
• Choose any suitable holes and slots on the base of the mounting
bracket for mounting the screws. If space is available on the
mounting surface, the screws should be spaced as far as possible
towards the corners of the mounting bracket to provide good
stability.
• Place the TU on the mounting bracket so that the holes on the side
flanges of the mounting bracket are aligned with the threaded
inserts on the TU. Use only the two screws and spring washers
provided to secure the TU to the mounting bracket. Not using the
supplied bracket screws could result in damage to the TU (especially
if screws are too long).

Installing the Antenna Unit (AU)
The antenna unit is composed of the antenna element array, necessary
high power and low noise amplifier systems and a tracking system.
Two AU versions exist: a 2-axis unit intended for land-mobile and fixed-
site installations and a 3-axis unit for the maritime environment.
Connection to both AUs is made by a TNC connector. The single co-
axial cable carries RX, TX, power, and tracking information.
Antenna Cable Lengths and Types
The radio has been type approved for use with the following cable
lengths and types:

16 LIGADO NETWORKS MSATeINSTALLATION GUIDE
CABLE LENGTH CABLE TYPE
6 m (20ft) RG223/U
18 m (60 ft) LMR240 (Equiv.)
45.7 m (150 ft) LMR600 (Equiv.)
Table 5 - Antenna Cable Lengths and Types
Vibrations
The antennas (2 and 3-axis versions) are designed to meet the following
operating vibration levels in any of three perpendicular directions
measured at the mounting base of the radome i.e. at the flange of the
standard mounting pole described above:
Radome Vibration
1.05 Grms with the following spectral density
5-20 Hz………….0.02G2/Hz
20-150 Hz………. -3dB/octave
And further,
Single Frequency Vibration
5-10 Hz with amplitude 2.54mm
10-15 Hz with amplitude 0.76mm
15-25 Hz with amplitude 0.40mm
25-33 Hz with amplitude 0.23mm
Vibration levels in a typical installation are usually much less than the
above-mentioned values. It is, however, the responsibility of the installer
to verify that the cited levels are not exceeded in any mode of operation
of the vehicle/vessel. In case of abnormal vibration, typically at a
resonance frequency, measures must be taken in order to displace the
resonance frequency or to dampen the vibration amplitude.

17 LIGADO NETWORKS MSATeINSTALLATION GUIDE
Installing the 2-Axis Land Mobile Antenna
WARNING: Avoid exposure to microwave radiation. Keep a
safe distance of minimum one (1) meter (39 inches) to the side and above
the antenna. Always power the MSATe down prior to disconnecting or
connecting the antenna. The antenna port is a 50 Ohm female TNC. This
line carries RF, signaling, and DC power for the antenna.
NOTE: Grounding the center conductor while power is applied to
the transceiver can cause the transceiver’s fuse and/or a fuse in the
vehicle to blow. No modifications should be made to the RF cable
under any circumstance.
Keep a clear line-of-sight to the satellite. Preferably, avoid all
obstructions within three (3) meters of the antenna. Obstructions less
than 15 cm (6 inches) in diameter can be ignored beyond this distance.
If the antenna is being mounted on a vehicle it is important to ensure
there is a clear line-of-site to the satellite(s) in all directions. After the
radio is commissioned and operational it is recommended that the signal
strength be checked while the vehicle is slowly driven in a 360º circle.
The signal strength should not vary significantly or be degraded in any
particular direction.
Do not locate the antenna close to interfering signal sources or receivers.
It is recommended that no other antennas be located within three (3)
meters of the MSATe antenna. If there is other equipment installed near
the MSATe satellite radio it is recommended to operate all equipment
simultaneously and verify there is no co-interference.
Mobile Installation
MAGNETIC (TEMPORARY) MOUNTING OPTION
For temporary use – or where drilling of holes is to be avoided – a
Magnetic Mount Installation Kit is offered. Ligado Product no: 101212
(SpaceCom reference part no: SPAC-AC-1016).
WARNING: [Insert warning about magnets and pacemakers/
medical devices if required]. Three (3) magnetic mounts each with an
adhesive force of at least 420 N (Newton) are required to secure the
antenna.

18 LIGADO NETWORKS MSATeINSTALLATION GUIDE
Figure 11 – 2 Axis Antenna with Magnetic Mounts
The Magnetic Mount consists of 3 individual high intensity magnets with
rubber coating. Each magnet having a stainless-steel M5 center bolt.
There are 3 “legs” on the antenna where the magnets are bolted in
place. Note the position of the three nylon rubber washers just below
and above each “leg,” the stainless-steel washer above the upper washer
and the M5 protective nut on top. Use torque of 2.5 Nm.
Now place the antenna with magnets on the roof of the car.
When installing the antenna cable, it’s important to protect against
moisture using self-amalgamating tape wrapped around the coaxial
connector or similar. Also, carefully secure the cable run from the
antenna at short intervals. An unsupported length of cable will vibrate
when driving and could over time result in a faulty connection.

19 LIGADO NETWORKS MSATeINSTALLATION GUIDE
Figure 12 – 2-Axis Antenna with Magnetic Mounts
Dismounting:
To dismount the antenna, clasp the antenna near one of the magnets and
lift up. When one magnet is loose, the other two will come loose with
little effort.
If the magnetic force is so large that the antenna cannot be dismounted
as described, it may be necessary to unscrew the antenna first and
remove the magnets separately.
PERMANENT INSTALLATION ON A VEHICLE
1. Always install antenna in a horizontal position, even if the surface –
roof of vehicle – is not horizontal.
The antenna has three drainage holes at the radome base.
2. Always install the antenna so clearance between the radome base
with drainage holes and mounting surface is no less than 5mm and
preferably 10mm, refer to figure 18.
In order to fulfill the above criteria 1. and 2., a set of bolts and washers is
defined for each individual installation, refer to figure 18.

20 LIGADO NETWORKS MSATeINSTALLATION GUIDE
Figure 13 - Antenna with Permanent Mount
The M5 stainless-steel washers are always used and positioned as
shown in figure 17.
The rubber washers are always used and positioned as shown in figure
17. The spacers are always used and positioned as shown in figure 17.
The 3 spacers will have identical length if the antenna is installed on a
non-tilting surface but may require individual length adjustment if the
surface is tilting. The M5 stainless-steel bolts will have identical length
if the three spacers are identical and may require individual length
adjustment if spacer length is different.
An Installation Kit is included with every antenna. It contains the
washers that are always used, three standard 10mm plastic spacers
used for a typical installation on a non-tilting surface and standard
length M5 stainless-steel bolts – Note length may have to be adjusted
to accommodate a tilting surface.
DRAINAGE OF THE ANTENNA
In order to keep the height of the antenna as small as possible and in
order to avoid the complex and often unreliable complete sealing of the
antenna, a simple mechanism in the form of three holes in the radome
(plastic enclosure) bottom is used. The holes are made so that water
– raindrops - are not likely to enter the radome and simultaneously
water that incidentally has entered the radome or moisture condensed
inside the radome is drained out simply by gravity. Correct function of
