PRESUBMISSION REQUEST
FORM
Fee: None
A presubmission conference is an opportunity for applicants, developer(s) and/or
consultants to meet with city staff to discuss preliminary studies or sketches of a
proposed project. At the conference the staff will make available information relating
to the proposed development. The intent is to identify and eliminate as many
potential problems as passible in order for the project to be processed without delay.
The conference should take place prior to detailed work by an engineer or surveyor,
however a site drawing must be submitted that has sufficient information to allow for
evaluation. Discussion topics will include such things as Yelm's Comprehensive
Plan, street design, storm runoff and retention, Shoreline Master Program, zoning,
availability of sewer and water, development concepts, other requirements and
permits, and the environmental impact. Staff notes are prepared and available to

SECTION 2 ANTENNA SITE SELECTION
GENERAL One ofthe most important factors to be considered for trouble-free,
high-quality signal reception from desired satellites is the location
of the antenna (i.e., the antenna site). For optimal signal reception,
it is important that the antenna site selected provides the following:
Operational Clearance. The site must allow clearance for
antenna movement (both elevation and azimuth) necessary
for aiming and maintenance purposes.
Clear Line -Of -Sight The site must allow clearance for
antenna to be aimed (pointed) at desired satellite(s) with
no obstructions between satellite(s) and any portion of the
reflector.
Absence Of Signal Interference. The site must be free of
strong microwave and other signal interference.
In order to evaluate the antenna site selected against the above
criteria, the antenna pointing position (i.c, aiming coordinates) for
the desired satellite(s) must be determined. The method of
determining aiming coordinates for desired satellites) and for
ensuring that the criteria are met is described below.
DETERMINING The location of each satellite, from which reception is desired, is
AIMING defined in degrees West Longitude (see Table 2-1). In order to
COORDINATES receive signals from a desired satellite, an antenna must be
positioned properly (i.e., have the correct elevation and azimuth).
The coordinates (degrees elevation and degrees azimuth) used for
positioning the antenna are referred to as aiming coordinates. The
following procedure, through use of an example, describes the
method for determining the aiming coordinates at a selected site for
a given satellite. This procedure is used here to evaluate the
selected antenna site before the antenna is installed; however, the
procedure is also used following antenna installation to accurately
aim the reflector at the desired satellite(s). The procedure is as
follows
Gsing information or maps provided by the FAA or other agency at
location of nntcnna site, determine the position of your selected
antenna site. This position must he defined in latitude (degrees North
of the equator) and in longitude (degrees West of the 0� Meridian,
which runs through London, England). The map in Figure 2-1 shows
relative longitudes and latitudes for U.S. locations. for example,
Atlanta. Georuia is 33.7 North. 84.4° W est.

a. Alone the bottom edge of the graph, mark the point
corresponding to the difference number obtained in step 3. In
the example above, the point is 46.6°.
b. Along the right edge of the graph, mark the point corresponding
to the selected antenna site latitude (determined in step 1). The
example point is 33.7°.

d. To determine the elevation aiming coordinate for the antenna•
follow the curved lines around to the left and estimate where the
reference point determined in (b) above would intersect the lett
edge of the graph. The example is about 27Q.
NOTE
For reference, elevation is measured up from the horizon and
azimuth is measured clockwise from the North.

ANTENNA SITE SELECTION
e. To detemtine Hie azimuth aiming coordinate for the antenna,
follow the curved lines upward and estimate where the reference
point determined in (b) above would intersect the upper edge of
the graph. The example is about 242°.
When using a compass to locate the azimuth aiming coordinate
determined in step 4.e above, it may be necessary to adjust the
compass indication (because of magnetic deviation) before pointing
tire antenna. In the example, the azimuth angle is 242°. however,
from Figure 2-4, Atlanta, Georgia, is about +P of magnetic deviation
from true North. 'I'hcrefore, to compensate for deviation, add I " to
our azimuth calculation: 242o + F = 243°, which is the actual
compass reading to use in pointing the antenna.
NOTE
The above method should be used in determining the antenna
aiming coordinates for both the satellite(%) from which
reception is currently desired and for satcllite(s) from which
reception may be desired in the fulure-
Azimuth and elevation aiming coordinates may also be determined by
formula using a digital calculator. In these formulas, X represents the
site latitude in degrees, Y represents the site longitude in degrees, and
Z represents the satellite longitude in degrees. For the southern
hemisphere, enter X as negative If west longitudes are entered as
positive numbers, define the longitude difference as:
D=Z-Y
If Last longitudes are entered as positive numbers, define the
longitude difference as:
D—Y-Z

VERIFYING Once the antenna aiming coordinates have been determined, it is
OPERATIONAL necessary to verify operational clearance (see Figure 2-5 for the
CLEARANCE 4.5 -meter antenna clearance requirements). This ensures that the
antenna movement necessary for both aiming and maintenance
purposes is not restricted.
4251988 SERIES 83454.5 -METER EARTH STATION ANTENNA SITE PREPARATION 2-7
ANTENNA SITE SELECTION
VERIFYING CLEAR Once tate operational clearance has been verified, it is necessary to
LINE -OF -SIGHT verify a clear line -of -sight. This ensures that the antenna may be
aimed at the desired satellite(s) without obstruction between the
satellite(s) and any portion of the reflector. When using the
satellite(s) aiming coordinates for a particular site, be sure that
there are no trees, buildings, power lines, etc., between the dish
location and the satellite. It is important that this clearance
includes the total dish surface area and that nothing is blocking any
portion of the dish surface.
VERIFYING For optimal signal reception, it is important that the antenna site
ABSENCE OF selected be free of strong microwave or other signal interface.
SIGNAL Microwave systems in the vicinity of a selected antenna site can
INTERFERENCE cause interference. If a known source of interference (e.g., a Bell
System microwave tower) is close by, it may be necessary to have
a site Survey, performed to determine if the site selected is suitable.

SECTION 3 FOUNDATION INSTALLATION
GENERAL The pointing accuracy of the installed antenna is determined by the
stiffness of the mount, the reflector. and the foundation. Therefore,
antenna foundation preparation is an essential part of antenna
installation.
ANTENNA The Series 8345 Manual 4.5 -Meter Earth Station does not require
CONSIDERATIONS critical foundation alignment because the antenna can be rotated on
its support ring through an azimuth of 360 degrees. However, the
motorized 4.5 -meter earth station with the optional Model 8862
Variable Speed Controller requires the foundation heading to be set
at the zero degree azimuth angle. See Figure 3-3 for reference
heading.
Proper electrical -,rounding shall be provided by the installing
contractor to meet local applicable codes. Depending on local soil
conditions, this may take the form of a buried grid or a suitable
copper stake. The antenna mount shall be electrically connected to
the ground.
Provisions must be made to provide suitable support for power,
RF, and control cables either by buried conduit or overhead
raceway. Lightning arrestors must be provided across all cables
leaving the antenna per applicable local codes and N.F.P.A. codes.
(Refer to Section 2 for information on required operational
clearances.)
Options For added ease of installation and a wider range of applications, the
following options are available:
Pier Foundation Kit (as a low-cost alternative to concrete slab foundation)
Portable base which will support the antenna in a 45 mph wind without
anchoring, or at survival if anchored properly to the ground.
ROTE
A slab foundation, Figure 3-3, is recommended with
the Model 8862 Variable Speed Controller option.
Roof Mounting Roof mounting is not recommended due to both mis-pointing and
wind loading considerations. Most roofs are not designed to
withstand the antenna loads, or to maintain the required stiffness.
If roof mounting is required, an engineering firm should be
employed to design a load Game appropriate for the roof, and to
insure that local building codes are followed.
42SI98B SERIES 83454.5 -METER EARTH STATION ANTENNA SITE PREPARATION 3-1
FOUNDATION INSTALLATION
FOUNDATION 'fhe loading for the above conditions is presented in Figures 3-I.
DESIGN The following information presents a typical pad foundation
CONSIDERATIONS design, If a special foundation design or load frame is required, a
qualified structural engineer who is familiar with local structural
codes should be employed. The foundation loading information
below should be used in implementing the design.
NOTE
ViaSat, Inc. does not represent or warrant that any
particular design or size of foundation is appropriate
for any particular locality or installation.
FOUNDATION Typical foundation designs for in -ground and surface -mounted feet
CONSTRUCTION are provided in Figures 3-2, 3-3, and 3-4. Foundations are designed
for 110 mi/h (177 km/h) wind loads. The foundation loads at 125
mi/h (201 km/h) winds apply only with the optional motorized
antenna stowed at 90° elevation angle.
Since soil conditions, building codes, and other factors vary for
different localities, persons installing antenna foundations should
obtain professional engineering services for the design and
construction supervision of antenna foundations.
The following items apply to the typical foundation designs and
corresponding instructions:
I. All reinforcing bars should conform with ASTM A-515-68, Grade 40
or Grade 60.
2. All concrete should conform to building code standards and have a
minimum compressive strength of 3000 psi at 28 days.
3. The antenna should be properly grounded to meet applicable local
codes. The ground cable from an antenna foot should be attached to
either a buried grid or a suitable stake, depending on local soil
conditions.
4. The typical foundations used in these instructions are provided for
illustration only. ViaSat does not represent or warrant that these
illustrative designs are suitable for any particular locality.
Consultation with a professional engineer may be necessary to

GENERAL 1IGTES:
/\, The foundation heading is critical to the antenna performance
when used with the optional 8862 controller.
2. Proper eleetrkal grounding shall be Provided by the installing contractor to meet
local opPlicable codes. Depending on local soil conditions, this may take the form
of a bunk grid or a suitable copper stake. The antenna mount shall be electrically
connected to the ground.
3. Provisions must be made to provide suitable support for power, RF and control
cables either by bused conduit or overhead raceway.
4. Ligntning arrestors must be provided across all cables leaving the antenna per
applicable local codes and N.F.P.A. Codes.
5. Refer to drawing 301749 for information on outline and clearance dimensions.
6. Use no nuts under the foot. 301636. The foot must rest flash on the concrete pad.
Use one washer and one flourooardon coated nut. 514339. per anchor bolt to secure
foot to pod. After the concrete is fully cured, torque the nuts to 100-110
foot—pounds.
A7 Pad required for optional 8862 controller installation. Pad location shall be positioned
behind the reflector and mount.
S. The minimum sale soil—bearing capacity is 2000 PSF,
9. Reinforcing bars shall conform to ASTM A615. grade 60.
10. Do not weld anchor bolts to reinforcing ban. This will remove the temper and reduce
the strength of the anchor bolts.
11. All concrete shall be building code standard weight 3000 p.s.i. Compressive strength
at 26 days.
12. Areas (6x12 in c h)[152 x 304di for mounting feet should be flat within
1/16 inch [1.6mm] and level with respect to one another within 1/8 inch [3.2mm].
13. Anchor bolts are .75 inch[19mm] diameter and must conform to ASTM A193 grade
87 or ASTM A325.
