1. Introduction
1.1 Purpose
The purpose of this manual is to provide the information required to enable the end user,
customer and installer to successfully install the VS61 antenna and controller and to
program the KA-160 for operation.
It is recommended that all personnel operating the VS61 systems know which type of
system they are dealing with, read and understand the basic terms, and are fully familiar
with the operation of these systems.
Although installation may be completed by personnel preferred or designated by the
customer, it is also recommended that personnel be trained in the SAMYUNG ENC for
more suitable equipment installation procedures, and trained by SAMYUNG ENC Inc.
experts in the relevant matters.
Section 2 of this document has been provided to ensure that ALL personnel are aware of the
specific safety hazards involved in the installation and configuration of the SAMYUNG ENC
equipment (e.g. electrical, static and RF radiation hazards).

2
2. Personnel and Antenna
This section defines the areas near or within the radiation area of the auto acquire
antennas currently deployed. It is recommended that ALL customers operating this
equipment become familiar with the radiation patterns of these units and strictly adhere to
the precautions outlined below.
2.1 Radiation Limits
Radiation limits are defined in terms of maximum permissible exposure (MPE), a
frequency-dependent level of radiation to which a person is subjected over some duration
of time. Besides being frequency-dependent, the MPE level and duration of time based
on the Specific Absorption Rate (SAR) of the human body depends on whether the area
around the antenna is controlled or uncontrolled. The definitions of these two types of
areas are quoted from OET 65, as follows:
“The FCC guidelines incorporate two separate tiers of exposure limits that are
dependent on the situation in which the exposure takes place and/or the status of the
individuals who are subject to exposure. The decision as to which tier applies in a given
situation should be based on the application of the following definitions.
Occupational/controlled exposure limits apply to situations in which persons are
exposed as a consequence of their employment and in which those persons who are
exposed have been made fully aware of the potential for exposure and can exercise
control over their exposure. Occupational/controlled exposure limits also apply where
exposure is of a transient nature as a result of incidental passage through a location
where exposure levels may be above general population/uncontrolled limits (see below),
as long as the exposed person has been made fully aware of the potential for exposure
and can exercise control over his or her exposure by leaving the area or by some other
appropriate means. As discussed later, the occupational/controlled exposure limits also
apply to amateur radio operators and members of their immediate household.
General population/uncontrolled exposure limits apply to situations in which the
general public may be exposed or in which persons who are exposed as a consequence
of their employment may not be made fully aware of the potential for exposure or cannot
exercise control over their exposure. Therefore, members of the general public would
always be considered under this category when exposure is not employment-related, for
example, in the case of a telecommunications tower to which persons in a nearby
residential area are exposed.

3
For the purpose of applying these definitions, awareness of the potential for RF
exposure in a workplace or similar environment can be provided through specific training
as part of an RF safety program. Warning signs and labels can also be used to establish
such awareness as long as they provide information, in a prominent manner, on the risk of
potential exposure and instructions on the methods of minimizing such a risk of exposure.”
The following conclusions can be drawn from these tables (Figure 2-1):
Power density between the feed flange and reflector is at a hazardous level and access
to this area must be prevented while the terminal is transmitting. Under no
circumstances should any part of a person’s body be placed in this region while the
terminal is transmitting.
Based on a controlled-area power density of 5 mW/cm2 over any 6-minute period, in
some cases less than 14.6 seconds of exposure is allowable in this region. Note that, in
general, an operator would not be manually adjusting the feed during a high-rate, high-
power transmission. Also note that the power density decreases toward the reflector (as
the beam widens from the feed), so the maximum exposure time increases as the
distance from the feed increases.
Near-field levels of radiation are below the controlled-area requirement, but in some
cases are above the uncontrolled area requirement. Although the nature of
transmissions is such that radiated power levels should not reach full power at any time,
there is no absolute guarantee of reduced transmission levels; therefore, access to the
near field of the antenna must also be restricted. Since the near field is contained within
a cylinder pointed from the reflector toward the satellite, we can compute the horizontal
distance from the front of the reflector to which access must be restricted. Table 2-1
computes this distance. At distances in excess of the tabulated limits, access can be
unrestricted. Between the antenna and the tabulated limits, access should be limited to
less than 10 minutes in any 30-minute interval.
Far-field levels of radiation are below the uncontrolled-area requirement and are
therefore not a concern.

Area
Figure 2-1 Defined Radiation Areas
Hazard Area (Between the feed and reflector): This is the highest power density region
because the area of power radiation (the feed flange) is smallest.
Warning Area (Near field): This is the area bounded by a cylinder within the same
diameter of the reflector, and which extends from the reflector toward the satellite for, in
the case of auto acquire systems, less than 75 meters (the exact distance depends on
frequency and the diameter of the reflector).
Far field: This is the area situated at some distance from the antenna, where the
radiation density falls off with the square of distance.

5
2.2 Recommendations
Access to the immediate vicinity of the antenna (reflector and feed) must be restricted to
trained customers and certified contracted/service personnel. No member of personnel
should interpose any of their body parts between the feed and the reflector while the
terminal is transmitting. At full output power, this region is dangerous in cases of
exposure of more than about 14.6 seconds.
At full output power, the near-field output of the auto acquire terminals exceeds the
allowable levels for continuous exposure in an uncontrolled area. This near field is a
cylindrical region which encloses the reflector and points toward the satellite. Because
many sites accommodating the auto acquire terminals are accessible to non-operational
personnel, these sites should be considered as uncontrolled and the recommended
precautions taken accordingly.
The primary precaution should consist in restricting access to the immediate area in
front of the reflector to short durations, which, according to worst-case assumptions,
means that access should be limited to less than 10 minutes within any 30-minute interval.
If limited-duration access cannot be insured, then no access should be allowed within the
distances specified in Table 2-1 below. (Table 2-1 assumes a member of personnel
standing 6ft tall at ground level. The horizontal distance must be scaled upward
accordingly if the members of personnel are at a level higher than 6 ft.).

3. Installation
3.1 Site Selection
Determine the optimum mounting location for the antenna radome assembly. It should
be installed where:
1. The antenna has a clear line-of-sight of as much of the sky as is practical. Choose a
location where masts or other structures do not block the satellite signal from the dish as
the boat turns.
2. The antenna is at least 5m away from other transmitting antennae (HF, VHF and
radar) which may generate signals with the potential to interfere with the VS series antenna.
The further away the VS series antenna is from these other antenna, the less likely is it to
be affected by their operation .
3. The antenna radome assembly should be rigidly mounted on the boat. If necessary,
reinforce the mounting area to assure that it does not flex due to the boat’s motion or
vibration.

3.2 Unpacking
Open the carton box using pliers and remove the packaging material carefully. Lift the
unit out of the box carefully. Do not turn the box and “roll” the unit out, or turn the box
upside down to remove it. Be careful when unpacking the equipment.
Lift carton box straight up

Remove the jig, screw, and tie used to protect the antenna from shipping damage after
opening the radome. If power is supplied to the antenna without remov ing the fixed parts
(jig, screw, tie), the antenna may be damaged.
The antenna should be secured using the fixed parts during transportation by truck or
another vehicle . So please keep the fixed parts in the event that the antenna is to be
moved to a different place or ready to be installed after ground testing.
Figure 3-4 Antenna Fixed Parts

3.3 Installing the Equipment Cables
The VSAT VS61 comprises two major sections: The Above-Deck Equipment (ADE) is
composed solely of the antenna radome assembly , which is mounted outside. The Below -
Decks Equipment (BDE) includes the Antenna Control Unit (ACU), satellite modem(s), and
all other items of ancillary equipment.
The ADE is connected with the BDE by two coaxial cables; the type of cable to be used
depends on the length of cable required .
NOTE : Unused coax connections (on the connector bracket) MUST be terminated with
a 75 ohm terminator.
NOTE : We recommend cable type according to cable length , as follows:
-within 20m: RG6
-within 50m: RG11
-within 100m: LMR400
-within 200m : LMR600
NOTE: Impedance of cable is 50ohm. Also you can select the other cable types.
However we recommend all attenuation of cable is under 20dB at 2.5GHz.
NOTE : When installing the cables, avoid the use of excessive force. Exercise caution
during installation of the cables to ensure that they are not severely bent ( within the
assured bend radius), kinked or twisted , and that the connectors are not damaged.
NOTE : Make sure that the cables have been passed through watertight fittings and/or
that they will prevent water from entering the ship once their installation has been
completed. After the cables have been routed and adjusted for the correct cable length at
each end, seal the deck penetration glands and tie the cables securely in place.

3.4 Mounting the Antenna Unit
3.4.1 Prepare the Support Post
1. Prepare the antenna support post for the radome. The radome must be bolted to the
support post plate. Make sure that the mounting holes have been drilled. Please refer
to the appendix for detail drawings.
2. Make sure that the antenna support post is painted appropriately for anti -corrosion.
3. Thread the TX and RX cables from below deck up through the cable access hole on the
deck. (Check the number of RF cables required).
4. The support post should be upright. Check the post angle carefully prior to welding the
post base to the deck. If it is uneven or not level, we ld the clips to the plate or place the
foam seal in position on the mounting surface .
5. Refer to Fig 3-5 below. The thickness and size of the support plate can be changed
according to the height of the support post
Figure 3-5 Diagram of a typical Antenna Support Post (Unit mm)

12
3.4.2 Hoisting the Antenna
1. Drill four bolt holes and cut out cable access hole at the mounting site.(Reference
appendix)
2. Place the foam seal in position on the mounting surface with the hole centered over the
cable access cutout
3. Position the base plate in place over the mounting holes and cable access hole, and
then align the radome base plate’s “Bow” label (shown in Figure 3-6) with the ship’s bow.
Figure 3-6 “BOW” Label of Radome Base
4. Connect the data/power, and RF cables form below d ecks to the base plate with a
7/16” wrench, applying 30 pound of torque. Check label both ends of each RF cable
to match its antenna base plate connector . Do NOT use Teflon gel on the cable
fittings as it reduces signal strength at high frequencies.
3.4.3 Installing the Radome Assembly
Install a flat and spring washers and a mounting bolt (supplied with the product) to each
mounting hole of the radome base from the underside of the mounting surface. Apply
Locktite to the threads of the mounting bolt up near the mounting surface a nd tighten each
of the 4 bolts to 24 in-lb (21 kg -cm) torque [finger tight, then about 1/4 turn tighter] with a
wrench.
DO NOT OVER -TIGHTEN . If the mounting bolt provided is too short, y ou will have to
install mounting bolts of the app ropriate length . If the bolt provided is too long, the ex cess
