Standard Cable Connections
In addition to the DC power connection, optional horn alert and ignition sense connections
may be made. These are all done using the four 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.
Horn Alert (Blue Wire - Optional Installation)
To install the Horn Alert, route and splice the blue wire (Horn Alert) as shown below.
Note that the Horn Alert option is not available in Dispatch Radio mode.

Basic Installation Procedure
While the installation of the MSAT-G2 mobile satellite radio is straightforward, it is essential
that the installation be done correctly.
The basic installation procedure is as follows:
1. Decide where you are going to install the antenna, TU and handset.
2. 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.
3. Determine the cabling required for the installation of each component.
4. Perform the installation of the antenna, TU and handset.
5. Connect the antenna and the handset to the TU
6. Connect the power to the TU.
7. Power up and commission the radio
Fixed-site Installation
Choosing a Location
It is important to choose a location for the antenna that will have a clear line-of-site to
the satellite(s). Preferably, avoid all obstructions within three (3) meters of the antenna.
Installation during windy conditions may be dangerous. The owner and installer assume all
responsibility to ensure that the equipment is properly installed with adequate structural
stability of mounting surface to withstand all loads (wind, weight, ice, etc.) and is properly
sealed to avoid leaks.
DO NOT ATTEMPT TO INSTALL OR DISMANTLE THE EQUIPMENT NEAR
ANY TYPE OF POWER LINE.
Safety Rules:
1) Select your installation site with safety as well as performance in mind.
2) Plan your installation carefully before beginning. Perform as many tasks as possible
while on the ground.
3) If any part of the equipment (i.e. antenna assembly) comes into contact with a power
line, do not try to remove it yourself. Contact your local power company.
4) When installing an antenna assembly, do not use a metal ladder.
5) If the antenna assembly starts to drop, get away from it and let it fall.
6) Verify that the antenna is properly grounded.
MSAT-G2 Installation Guide 10

Lightning Arrestors
The applicable electrical code(s) may require that lightning arrestors capable of supporting L-
band transmissions be installed on all cabling between the fixed-site antenna and the structure
which the equipment is housed in. It is also suggested that any structure containing the radio
be equipped with a lightning rod connected to the ground. The professional doing the fixed-
site installation is responsible for determining all such requirements with the customer and
installing the equipment such that it complies with all applicable standards.
Installing the TU – Fixed-site and Vehicle
Installation – General
1) For ease of service, route the radio cables and power cables together.
2) Always disconnect the negative side of the vehicle battery prior to any electrical work.
3) 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.
4) Use cable ties every 30 – 45 cm (12-18”).
5) The TU can be mounted in either the horizontal or vertical position.
6) 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.
7) The ground line should be connected directly to the vehicle’s battery ground.
8) Install the TU in a protected but ventilated area (inside building or vehicle). Allow
at least a 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 servicing.
9) The TU is not waterproof.
10) Always provision the wiring into the TU with a drip loop.
11) With the exception of the TU to Antenna cable, do not route the cables outside
the vehicle.
Mounting Bracket Information
NOTE: Use care when drilling through the body of the 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.
MSAT-G2 Installation Guide 11

Instructions for the installer:
1. The mounting bracket should be used for mounting the TU.
2. 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.
3. 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.
4. 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).

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:
Figure 15 – Antenna Cable Lengths and Types
Installing the 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 MSAT-G2
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 MSAT-G2 antenna. If there
is other equipment installed near the MSAT-G2 satellite radio it is recommended to operate
all equipment simultaneously and verify there is no co-interference.
SpaceCom SPAC-AS-MSV220 Land-Mobile / Fixed-site Antenna
Magnetic (Temporary) Mounting option
For temporary use – or where drilling of holes is to be avoided – a Magnetic Mount
Installation Kit is offered. SpaceCom part no: SPAC-AC-1016.
Three (3) magnetic mounts each with an adhesive force of at least 420 N (Newton)
are required to secure the MSV220 antenna.
Figure 16 – SPAC-AS-MSV220 2-axis Antenna W/ Magnetic Mounts
MSAT-G2 Installation Guide 15

Magnetic Mount Installation
The Magnet Mount consists of (3) three individual high intensity magnets with rubber
coating. Each magnet has a stainless steel M5 center bolt.
First attach the magnets to the antenna. There are (3) three “legs” on the antenna where
the magnets are placed. Note the position of the two nylon (plastic) washers just below
and above each “leg”, the stainless steel washer above the upper nylon washer and the M5
protective nut on top.
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
amalgating tape, or similar, wrapped around the coaxial connector. Also be careful with the
cable run from the antenna and secure it at short intervals. An unsupported length of cable
will vibrate when driving and could negatively affect the connection over time.
Dismounting:
Grab the antenna near one of the magnets and lift. When one magnet is loose, the other
two are easy to “break off”. In some situations the force of the magnet may be too great
and it will be necessary to unscrew the antenna first and remove the magnets separately.

Permanent (Mast) Mounting
For permanent mounting of the SPAC-AS-MSV220, a special Pole Mount Installation Kit is
available. SpaceCom part no.: SPAC-AC-1017. Designed for easy installation, it ensures proper
drainage of the antenna, galvanic insulation and is able to withstand the rigid mechanical stress.
Figure 18 – SPAC-AS-MSV220 2-axis Antenna W/ Optional Pole Mount
SPAC-AS-MSV220 Antenna Pole Mount Installation
The Pole Mount is made of stainless steel. The antenna is placed on the triangular top and
the pole fixed using the U-clamps. (To a short mast or similar)
First mount the antenna on top of the pole with (3) three pcs. M6x50 mm bolts. The (6) six
pcs. nylon washers are used just below and above the antenna “legs”
The 44 mm U-clamps are placed around the pole mount, leaving the 50 mm U-clamps for
the mast. Small tolerances in the mast diameter can be compensated by simply bending the
U-clamps slightly.
When installing the antenna cable, it is important to protect against moisture – using self
amalgating tape, or similar, wrapped around the coaxial connector. Also be careful with the
cable run from the antenna and secure it at short intervals. An unsupported length of cable
will vibrate in strong winds and could negatively affect the connection over time.
