4.2 Antenna Installation
WARNING
Electrical Storm Hazard
Electrical storms can cause the antennae to be charged to high voltages. Do not touch outside of
equipment, or grounding wires and rods during electrical storms. Failure to observe this warning
can cause serious injury or death.
4.2.1 Placement
Figure 4.2.1-1: Antenna Location, Un-obstructed Sky
The NOMAD MXU system relays telephone conversations via satellites in Low Earth Orbit (LEO) around
the world. Only one satellite at a time is in contact with the MXU console. Because of the rotation of the
earth, the satellite may be moving, in a south/north direction across any part of the sky, while it maintaining
contact with the MXU console. Before the satellite departs over the north horizon, it will hand off the
telephone conversation to the next satellite arriving on the south side of the horizon. If the antennas are not
correctly located, the satellites will not have a “line of sight” with the antennas and the service will be
unreliable.
The antennas must be located to provide a clear view of the sky, from horizon to horizon. Figure 4.2.1-1
illustrates three possible cases.
• Case 1 The NOMAD MXU system will work intermittently because half of the sky is blocked by a
large building. This will result in some passing satellites not having a clear “line of sight” to the
antennas.
• Case 2: This NOMAD MXU will probably work better than in case 1; however, depending on the size
of the tree, intermittent operation of the NOMAD MXU is probable because of the addition attenuation
and the periodic blockage of the signal between the antenna and satellites.
• Case 3: This will give the best operation of the NOMAD MXU system because there is direct “line of
sight” to the satellite regardless of its location in the sky.
Case 1: NO Case 2: MAYBE Case 3: YES

4.2.2 Installation
Figure 4.2.2-1: Antenna / Mast Mounting
Figure 4.2.2-1 depicts the Nomad Antenna Assembly Kit (01-P43410F) as it would be configured for a
quad antenna system and mounted on a flat surface. None of the cabling is depicted above.
Step 1: Mast Assembly: The Antenna Mast kit 01-P43460F001 should be assembled first.
Step 2: Install Mast: The mast must be located in the position determined in section 4.2.1. The mast
assembly may be mounted on a flat or pitched (slanted) surface. It will be configured as a two or four
antenna system in step 5 below. Lag bolts, item 8 (9178546), are provided to attach the universal tripod
item 6 (Ronnie 5) to any surface material that will accept the lag bolt. Flat washers, item 10 (90108A029),
are to be installed on the lag bolts prior to installation on the tripod foot. Tarpads, item 7 (78), are to be
installed between the foot of the tripod and the mounting surface to waterproof the attachment point. All of
the lag bolts, except 2 that will be used later for installation of the surge suppressor mounting bracket,
should be used for mounting the mast assembly. If the surface is concrete or some other material that will
not readily accept the lag bolt, lag bolt anchors, item 9 (97039A029), have been included in the kit.
Step 3: Lighting Rod: Install the 3-way fitting, item 13 (07-P43417F001), over the circular portion of the
lightning rod mount, item 12 (07-P43416F001), and secure the set screws using the 5/32 allen wrench, item
22 (7122A21), included in the kit. Prior to tightening the set-screws, the 3-way fitting should be located as
far onto the lightening rod mount as possible. Secure the lightning rod mount to allow installation of the
lightning rod, item 11(585CCAT-2/0). Prepare the lightning rod for installation by removing all of the

fasteners from the threaded end. Re-install one each of the nut, lock washer, and flat washer. Thread the
lightning rod into the mount and secure the jam nut.
The lightning rod mount shall be secured to the top of the mast by engaging the circular cut out portion of
the mount to the top of the mast and installing the u-bolts, item14 (3043T78), and lock washers, item 15
(91102A031).
Step 4: Grounding Cable: The lightning rod that extends from the top of the array has a grounding cable
(not shown above) attached and should be attached to the building ground in accordance with the
instructions in Section 4.3, step 5, below.
Step 5: Antennas: The Antenna kit 01-P43455F001 is now required to continue the assembly. The cross
bar(s), item 2 (07-P43411F001), slip through the 3-way fitting and should extend from the fitting an equal
distance on each side. Tighten the set-screws with the enclosed allen wrench to secure the cross bars.
The metal plate that the antenna, item 4 (07-P43412F001), is supplied with, is to be replaced by the cable-
mounting bracket, item 3 (07-P43415F001), included in the kit. If necessary, reorient the u-bolts to allow
the antenna, when installed on to the cross bar, to have the cone shape perpendicular to the cross bar. Install
the antenna onto the cross bar so that the antenna and it’s clamps are resting on the tape on the end of the
cross bar, and the cone is inverted above the cross bar as shown. The plastic end caps, item 5 (FCR-16),
that have been supplied shall be installed on the end of the cross bars.
Installation of the surge suppressors and coax cables are described in the following section.

4.3 System Interconnections
Figure 4.3-1: MXU Console Interconnections
Interconnections between the antennas, power and the MXU console are illustrated in Figure 5.4-1. Each
step numbered in Figure 5.4-1 is discussed below in the following paragraphs.
4.3.1 Building Ground
Step 1. Locate the “Building Ground”. It is extremely important to ground the antenna assembly, surge
protectors, and power outlet to the central building ground. If not properly grounded, a nearby
lighting strike can easily damage the MXU system and can cause personal injury or death. In figure
4.3-1 the building ground is illustrated, in view G, as a ground rod. If any doubt exists as to the
location of the building ground consult with a local certified electrician.
Step 2. Verify the MXU power outlet, view “F” will accept the three prong electrical pug (Line Item 28)
supplied with the MXU shipment. Consult with a certified electrician to verify the power outlet is
properly wired and verify ground is properly connected to the building ground. If the power cord
does not match the power outlet, the user is responsible for securing the correct power cord. Refer
to Pre-Installation Checklist, Check 10, Appendix “A”.

Step 3. Install the four surge suppressors (Line Items 26) just inside the building were the coax cables W1
(Line Item 23) enter the building as illustrated in view “E” of Figure 5.4-1. The surge suppressors,
are mounted to the surge suppressor bracket, Line Item 17), which has been mounted with the 2
remaining lag bolts, and lag bolt anchors (if required).
Step 4. The surge suppressor bracket needs to be attached to the same building ground, view E, that the
antenna mast and power outlet are grounded to. The enclosed ground wire, (Line Item 18), lug,
(Line Item 19) nut and bolt, (Line Items 20 and 21) will allow the attachment of the ground wire
to the surge suppressor bracket
Step 5: Connect the bare cable from the lighting rod to the building ground as illustrated in view “C” and
view “G”.
WARNING
Improper Lightning Rod Grounding Hazard
Ensure the lightening rod is properly grounded before connecting the equipment. Failure to
observe this warning can result in serious injury or death by electrocution.
Step 6. Connect the short (1ft) coax wire W3 from one of the antennas (View “B”) to coax W1 (View “A”)
and secure to the antenna’s crossbars. Repeat for the other 3 antennas.
Step 7. Connect the long coax W1 (30 feet) from the cross bar to one of the lighting arrestors (View “E”).

Go to section 6.2 “Telephone Problems”
5.3 Monitor Station Check (Optional)
It is possible to configure a user supplied personal computer (PC) to interface with the NOMAD MXU
console through the RS232 connector on the front panel, This will enable the user to monitor MXU
activities and retrieve diagnostic logs from the MXU. For details on setup and operation of the monitor
station refer to the administrative manual.
5.4 Satellite Link Checks (Optional)
If the “Ready Light came on during the power up sequence described in section 5.1, at least one channel
exists between the NOMAD MXU console and the Iridium satellites. There are several ways to determine
if all RF channels, antenna, coax cables, and the RF side of the MXU console are operating correctly.
Methods 1 and 2 are preferred for verification but method three can be used for verification or isolation of
the problem to either the antenna and coax, or to the RF portion of the MU console.
1. If the user setup the monitor station, described in section 5.3, the diagnostic logs can be retrieved and
the signal strength between the satellites and the MXU can be verified. Refer to the Administration
Manual for details.
2. If the user did not setup the monitor station, the Gateway can retrieve the diagnostic logs, over the
PSTN modem connection, and inform the user of the status of the Iridium channels. Refer to the
Administration Manual for details. If one of the channels is not present or has a weak signal refer to
section 6.3.
3. If the Ready LED on the MXU’s front panel came on, all four RF channels can be verified without a
diagnostic log as follows.
First Step: We need to determine the good and bad RF channels as follows:
a. Power Down the MXU
b. Disconnect all the antenna cables but one, from the back of the MXU.
DRAFT COPY
NOMAD MXU Installation Manual 3:36 PM 02/12/99

c. Power on the NOMAD MXU.
d. If the Ready LED comes on within 3 to 5 minutes mark the Coax cable and MXU connector as
good. Else mark both “questionable”.
e. Repeat steps a,b,c & d for each of the three remaining channels.
Second Step: We need to determine which “Questionable” cables are bad.
a. Power Down the MXU
b. Disconnect all the antenna cables from the back of the MXU.
c. Connect the questionable coax from a bad channel to a good MXU channel.
d. Power on the NOMAD MXU.
e. If the Ready LED comes on within 3 to 5 minutes mark the questionable Coax cable good. Else
mark the cable bad.
f. Repeat steps a,b,c d & e for each of the three remaining “questionable” cables.
TO REPAIR ANTENNA/ COAX CABLES, REFER TO Section 6.3.
Third Step: We need to determine which “Questionable” MXU RF channels are bad.
a. Power Down the MXU
b. Disconnect all the antenna cables from the back of the MXU.
c. Connect a “good” coax to a “questionable MXU channel.
d. Power on the NOMAD MXU.
e. If the Ready LED comes on within 3 to 5 minutes mark the questionable MXU Channel “good”.
Else mark the RF Channel “bad”.
f. Repeat steps a,b,c d & e for any remaining “questionable” MXU RF channels.
NOTIFY THE GATEWAY OF ANY BAD MXU RF CHANNELS.
