instructions detailed in the installation specification.
The antennas, when initially installed, operate in the Ku fre-
quency band. At a future time, they can be altered to operate in
the Ka band by changing the feed support arm and radio.

The DIRECWAY system The DIRECWAY®system consists of satellites, satellite anten-
nas, terminals known as IDUs, and intra-facility link (IFL) cable.
The DIRECWAY system provides Internet or corporate intranet
connectivity via satellite through DIRECWAY terminals.
For the purpose of illustration, Figure 1 uses a DW6000 to show
the basic functionality of an IDU within a DIRECWAY network.
Other IDUs, such as the DW4020, function in a similar way.
Some IDUs can be connected to more than one device, using one
of several methods. See the specific IDU manual for details.

Cable specifications These cable specifications are the minimum required. If the cable
installation does not meet the minimum requirements, future applica-
tions may require that the entire cable installation be replaced with
the minimum required cable.
Grounding and cable choice
The choice of grounding scheme may affect the choice of cable. Note that meeting the
National Electrical Code grounding requirements is easier if you use RG-6 with solid copper
center conductor and quad shield. However, you can also meet the requirements by using
RG-6 with solid copper center conductor or copper clad steel conductor only and grounding
the mast as described in Chapter 5 – Grounding requirements, on page 77.

Important: A higher grade of cable can be used for an installation where a lower grade is
specified. For example, an RG-6 cable with solid copper center conductor and quad
shield can be used for installations where the cable length is less than 300 ft. Never use a
lower grade of cable than specified. Be sure to record the grade of the cable used for the
installation. The grade is printed on the cable every few feet. Never use a cable which
does not have the manufacturers name and its grade clearly printed on it!

Note: Do not use splitters.
Note: Use plenum grade cable only if the cable is to be run in plenum
space which is carrying return air for the air circulation system, or when
local laws require it. Never use plenum grade cable outside a building.

Chapter 2
General requirements
This chapter covers general requirements that need to be
considered and planned for prior to installing the
Ku/Ka-upgradeable antennas:
•Installation safety policies
•Permits, inspections, and approvals on page 8
•Possible restrictions on page 9
•Personnel requirements on page 9
•Tools needed for installation on page 10
•Items needed for installation
To avoid delays, make sure you have the tools and items required
for installation and commissioning before you go to the
installation site. To prepare for installation, review the items
listed in Table 1 and Table 2 and make arrangements to obtain
any tools you don’t have. You may need general purpose tools in
addition to the specific tools listed here.
Installation safety
policies
All DIRECWAY-SP earth stations have radiation levels between
the feed horn and the reflector that exceed the maximum
permissible exposure (MPE) limits set by the FCC for the
protection of the general public. DIRECWAY-SP earth stations
can also, in certain operating modes, transmit RF radiation at
levels above the MPE limit in the cylinder projecting outward
from the reflector towards the satellite.
DIRECWAY-SP installation
policy document
All HNS policies relevant to installing DIRECWAY-SP earth
stations are detailed in the document Policy for the Installation
and Operation of DIRECWAY-SP Two-Way Ka-Band Satellite
Earth Stations (HNS-30794). You must read this document and
sign and return the form it contains certifying that you have read
it and will abide by the policy.

DIRECWAY-SP installation
policy and this manual
This manual specifies how to install the antenna mount so that the
general public is protected from prolonged exposure to RF
radiation above MPE levels. All installations must be done in
such a manner that the general public cannot access either the
volume of space projecting outward in front of the reflector
towards the satellite, or the volume of space between the feed
horn and reflector.
Installation of DIRECWAY-SP earth stations must conform to all
the safety alerts below. Read them all and make sure you
understand them. Keep these safety alerts in a ready accessible
place for easy reference.
General safety
specifications
The antenna must be installed such that only in locations that are
not readily accessible to children and in a manner that prevents
human exposure to potentially harmful levels of radiation.
To accomplish this, there must be controlled access to the antenna
(i.e., the earth station). There are two ways to accomplish
controlled access, as described in the following safety alert. More
specific instructions regarding the size of fenced installations and
signage for fenced and roof installations are in the manual
sections describing those types of installations.
Note: A second layer of the safety process is the inclusion of a
safety mechanism in all DIRECWAY-SP stations that averages the
radiated power over time to ensure that the MPE levels are not
exceeded in the cylinder in front of the antenna towards the
satellite. The mechanism activates after the system is installed and
functioning. Because installers do not configure or operate the
mechanism, it is not described in this manual.
