NAVIGATOR MODEL 38-III STEERABLE ANTENNA SYSTEM
OVERVIEW
Superior Satellite Engineers is pleased to provide our three-axis-motorized Navigator 38-III Steerable Antenna System
configured with the Patriot 3.8-meter reflector. The Patriot 3.8-meter satellite antenna is recognized world-wide as
the industry standard where 3.8-meter antennas are required. Further, the new-generation domestic satellites all
exhibit high output - EIRP - values that will provide re-Broadcast audio and video quality for even the most demanding
venues. An important mechanical feature of the Navigator 38-III is that we motorize all three - azimuth, elevation and
feed system - axes in order to provide outstanding mechanical and wind-loading characteristics. And, note that the
elevation drive unit attaches to the Mount at the lowest point, thus most of the loading forces are directed to where
the Mount is the most stable.
The Navigator 38-III is also available in bolt-on retrofit configuration for existing 3.8-meter Patriot Antennas.
REFLECTOR
The reflector we have selected to integrate with the Navigator 38-III is produced by Patriot Antennas and, as alluded to
above, it is recognized as the world-wide industry standard for 3.8-meter antenna systems. The sixteen panel
reflector features radial-beam construction for a highly accurate surface tolerance. All components can be handled by a
two-man technical team so that no lifting devices are required. Complete antenna patterns are available for the Patriot
3.8-meter Reflector on request.
FEED SYSTEM
The standard Feed System features both C and Ku-band capability. The Controller simply selects the polarization appropriate
to the downlink requirement. A popular upgrade for the Feed System is our SSE-ESR-124D. This unit is our fully motorized,
four-port - dual polarization C and Ku-bands - system and it provides access to any frequency and format. Another important
consideration is that the Controller can provide backup in case of a failed LNB by simply rotating the feed horn 90?.
"Digital-Ready" C and Ku-band LNBs are included with both Feed Systems options.
MOUNT
The Navigator 38-III is our steerable mount interface and is a proprietary product of Superior Satellite Engineers. It
features discreet Thompson Saginaw Drive units for both azimuth and elevation that provide maximum mechanical and structural
capability. This is a dramatic departure from the ordinary "polar" type of mount generally associated with 3.8-meter antennas
wherein a single drive system provides all the mechanical adjustment. In conjunction with the Controller, the Navigator 38-III
System provides repeatability and pointing accuracy. It can also be programmed to access 'inclined-orbit" satellites.
The unique two axis Pole Mount (6"X 12' Schedule 80 pipe) features distinct installation advantages; it can be simply cemented
into the ground in most cases and can be roof mounted using a Baird non-penetrating mount system.
CONTROLLER
We have selected the Research Concepts Model RC 2000A to provide the positioning requirements associated with the Navigator 38-III.
The Model RC 2000A can be pre-set for fifty antenna positions and can also be upgraded with "tracking" capability for inclined-orbit
satellites and for automatic "peaking" once the desired satellite has been accessed. With available Autopilot Software package, the
RC 2000A can handle event scheduling and Receiver tuning. It also features communications capability for off-site operations.
APPLICATIONS
Cable Television
The Navigator 38-III has become very popular in CATV Systems where it is used
for Pay-per-view and ad hoc Programming as well as a backup system that can
access any satellite and tune for any format and frequency.
Broadcast Television
With the new-generation high-output satellites, the Navigator 38-III has proven
capable of generating re-Broadcast level video and audio for the most demanding
applications. It can be used as a primary or backup unit and can be easily and
economically roof mounted.
Education and Medical
Other popular applications for the Navigator 38-III have been for education
purposes. Both the medical and education fields have found it to be a great
tool to access instructional satellite-delivered Programming.
