1.1. Dual Antenna Configuration
The basic premise for a dual antenna configuration is to provide un-interrupted TV services to the below decks
distribution system. In some vessel installations, clear view to all AZ bearings is not possible, which may be due
to blockage created by the vessels superstructure, masts or stacks. The theory in installing dual antennas is that
both antennas will be tracking the same satellite but only one antenna will be blocked at any given time. If
properly configured the Sea Tel antenna system will provide an output to an arbitrator when the antenna is
blocked, or goes into unwrap. The arbitrator will then route signals from the un-blocked antenna to the below
decks distribution. To avoid unnecessary switching, the arbitrator will only switch when the current “active”
antenna becomes blocked or goes into unwrap. Blockage/Unwrap are the primary conditions that will provide the
switching signal to the arbitrator. However, several other conditions which effectively make the antenna “not
available” can generate the signal as well: If the antenna:
•Loses satellite signal
•Loses Network ID (NID)
•Has a pedestal stability error
1.2. Installing the Antennas
Typically the two antennas are mounted with one on the port side of the vessel and the other on the starboard
side (ie left & right side of a mast). Another (less desirable) option would be with one a little forward of the mast
and the other aft of it. Both antennas will be installed per the instructions in the installation manual, HOWEVER,
to ensure that both antennas do not unwrap at the same time, align the “Secondary Antenna” with its’ BOW
marker to the Stern (or 180.0˚ from “Primary Antenna A”s’ orientation).
1.3. Blockage Zone Plotting
For the arbitrator switching to work properly the blockage zones for each antenna must be programmed into its’
LMXP. Refer to the Blockage Zone information in the Installation Manual to determine the values to enter for up
to 4 blockage zones, for each antenna. The blockage zones will NOT be the same values for both antennas,
because the antennas are mounted in different locations. The blockage (also triggered by Unwrap) output from
each LMXP will allow the arbitrator to automatically route signals from the antenna which has good signal from
the satellite to the below decks & distribution equipment. Once properly configured, this configuration eliminates
the need for any operator intervention to maintain un-interrupted TV services.
1.4. 4 Switch Dual Antenna Arbitrator Panel Assembly (Sea Tel PN 33-145007-A)
NOTE: This document refers to your PRIMARY antenna system (Antenna and its’ LMXP), regardless of which
location (Port or Starboard) the antenna is mounted in. On power-up of the system, or on loss of power to the
Dual Antenna Arbitrator panel, the signals from the PRIMARY antenna will be routed to the below decks
distribution.
When the primary antenna is blocked, signals from the SECONDARY antenna (Antenna and its’ LMXP) will be
routed to the below decks distribution.
If both antenna systems are blocked, or un-blocked, the switches on this panel will remain in their previous state
(logic latched).
When the secondary antenna is blocked, signals from the primary antenna will again be routed to the below
decks distribution.

4 Connect the Matrix Switch coax cables:
•Connect the Low band Vertical/RHCP (Blue) coax from J3 (bottom) connector of Coax Switch
SW1 to either the Vertical Low input on the Ku-Band Multiswitch, or the 13V input on the SWM
switch, or to a splitter connected to both of these ports.
•Connect the High band Vertical/RHCP (Green) coax from J3 connector of Coax Switch SW2 to
either the Vertical High input on the Ku-Band Multiswitch, or the 13V/22kHz input on the SWM
switch, or to a splitter connected to both of these ports.
•Connect the Low band Horizontal/LHCP (White) coax from J3 connector of Coax Switch SW3 to
either the Horizontal Low input on the Ku-Band Multiswitch, or the 18V input on the SWM switch,
or to a splitter connected to both of these ports.

either the Horizontal High input on the Ku-Band Multiswitch, or the 18V/22kHz input on the SWM
switch, or to a splitter connected to both of these ports.
1.6. Setup of the LMXP’s
Refer to instructions in your Sea Tel TV/TVHD Installation manual.
1 Energize the Arbitrator panel by plugging in the power cable to an A/C power source.
2 Energize both antenna systems by applying power from the front panel of each of the LMXP’s.
3 Energize all other below decks and distribution equipment.
Primary Antenna - LMXP:
4 Connect a computer to the Ethernet LAN port (J4B) on the rear panel of the Primary LMXP.
5 Log into the Primary LMXP and select the Communication Interfaces page.
6 Configure the Addresses fields as is appropriate for the LAN onboard the ship.
7 Select the Configuration – System page to program blockage AZ & EL LIMIT values into the Primary
LMXP. The LMXPs allow up to FOUR blockage zones to be programmed for each antenna. NOTE:
The blockage zones will NOT be the same values for both antennas, because the antennas are
mounted in different locations.
8 Click on the compass rose graphic in the banner of the page and press “Shift” + “B”. The blockage
zones are each represented on the compass as a transparent red wedge overlaid on the compass
(using the start and end positions of the programmed blockage zones).
9 Select the Auto – Satellite Search page and Target the antenna to a desired satellite (both LMXP’s
will be targeted to the same satellite). Refer to the installation manual if the desired satellite has
not been set up yet and must be created now.
10 If the desired satellite is found skip to step 12. If the desired satellite is not found, Select the Tools –
Position Antenna page.
11 Turn Tracking OFF. Using the UP/DOWN/LEFT/RIGHT arrows to manually move the dish to acquire
the desired satellite.
12 Turn Tracking ON.
13 Positively verify that the satellite found is the satellite that was targeted.
14 If the trims have NOT been previously set, click the Auto Trim button. If they have been previously
set, there is no need to trim again.

19 Log into the Secondary LMXP and select the Communication Interfaces page.
20 Configure the Addresses fields as is appropriate for the LAN onboard the ship. The IP Address of
this LMXP must be set to one greater than the IP Address of the Primary LMXP (ie, if the Primary
LMXP is set to 10.1.1.100, the Secondary LMXP must be set to 10.1.1.101). All of the other
Addresses are set to the same values as are set in the Primary LMXP.
21 Select the Configuration – System page to program up to 4 blockage AZ & EL LIMIT values into the
Secondary LMXP. NOTE: The blockage zones will NOT be the same values for both antennas,
because the antennas are mounted in different locations.
22 Click on the compass rose graphic in the banner of the page and press “Shift” + “B”. The blockage
zones are each represented on the compass as a transparent red wedge overlaid on the compass
(using the start and end positions of the programmed blockage zones).
23 Select the Configuration - Reflector page and enter a preliminary AZ Trim of 180.0.
24 Select the Auto – Satellite Search page and Target the antenna to a desired satellite (both LMXP’s
will be targeted to the same satellite). Refer to the installation manual if the desired satellite has
not been set up yet and must be created now.
25 If the desired satellite is found skip to step 27. If the desired satellite is not found, Select the Tools –
Position Antenna page.
26 Turn Tracking OFF. Using the UP/DOWN/LEFT/RIGHT arrows to manually move the dish to acquire
the desired satellite.
27 Turn Tracking ON.
28 Positively verify that the satellite found is the satellite that was targeted.
29 The AZ trim was preliminarily set to 180.0, Auto Trim button.
30 Enter the name of the ship in the Ship Name field.
31 Enter the name of the antenna (ie Starboard Side TV Antenna) in the Antenna Name field.
