TRIA Components
The Transmit Receive Integrated Assembly (TRIA) consists of two
main components. The Feed Horn Assembly is responsible for
directing the Transmit signal or capturing the Receive signal.
This assembly has two components:
Polarized Feed Horn
Ortho-Mode Transducer
The Transceiver converts the signal frequency between the
satellite signal and the modem.
VS1300 pTRIA
VS1300 eTRIA
VS1100/VS1200 TRIA
Anik F2 Covered TRIA
WildBlue 1 and AMC 15 Covered TRIA
Feed Horn Assembly Models
The Feed Horn Assembly directs, separates, and filters the
satellite Radio Frequency to and from the satellite. Each
component supports the following essential functions:
There are various types of Feed Horn Assembly models and each is
configured at the manufacturer and is not designed for field
modification. The Feed Horn polarization position determines which
satellite the TRIA communicates with.

Assembly:
VS1300 pTRIA
VS1300 TRIA
VS1100/VS1200 TRIA
Anik F2 Covered TRIA
The covered Feed Horns are available in the left Polarization. It
is not necessary to remove the cover to determine the Polarization
information. It is easily viewable from the outside.
WildBlue 1 and AMC 15 Covered TRIA
The covered Feed Horns are available in the right Polarization. It
is not necessary to remove the cover to determine the Polarization
information. It is easily viewable from the outside.
The VS 1100/VS1200 TRIA and VS1300 eTRIA are sealed units and do
not require a weather cover.
TRIA Handling
It is important to handle electronic equipment with care to avoid
damaging delicate components. The TRIA is such a component. Keep
the TRIA in the shipping box for transport to the installation
site. Place the boxed TRIA in a place where it will not be
dropped, shaken, or experience sudden jolts.
Once at the installation site proper handling of the TRIA is
required. Commonly, technicians grasp the TRIA around the base of
the feed horn. Grasping the TRIA by the plastic cap applies
damaging stresses to the plastic cap and may cause the seal to
break and/or tear when the “lip” at the base of the cap is caught
by gripping the TRIA in this way.
Proper TRIA Handling
Improper TRIA Handling
Maintaining the integrity of the cap and the glue seal is critical
to preventing TRIA water damage. Avoid contact with the feed cap,
especially the lip as the feed cap is not designed as a lifting
point for the TRIA assembly.
Carrying a TRIA up a ladder
It may be cumbersome to carry a TRIA up a ladder. Commonly the
TRIA is held in one hand, leaving the other hand available to hold
on to the ladder. A better way to carry the TRIA is with a sling.
Construct a secure sling from a 30-inch section of rope or twine,
tied into a loop. Wrap the sling around the base of the polarizer.
Attach the sling to a belt clip or tool belt, leaving both hands
free to climb the ladder. This is a secure position for holding
the TRIA, and keeps the feed cap elevated to reduce risk of
damage. Avoid dropping or banging the component as this may damage
internal components.
Construct a sling with rope or twine, and loop the sling at base
of polarizer
Pull loop snug around the base
Grasp the sling and attach to belt or tool belt
The following sling positions are not recommended because the Feed
cap is vulnerable to damage.
Transceiver Model VS1300 eTRIA
The eTRIA, which comes in 3W and 6W versions has the following
features:
Smaller, more compact design
No bracket is required – the eTRIA attaches directly to the
shortened, narrower boom arm
Lighter weight – the VS1100/1200 TRIA weighed nearly 7 lbs
whereas the eTRIA weighs less than 3.5 lbs
Single COAX cable is connected through the boom arm, not on
the outside using ties as with previous models for easier
installation
Transceiver Model VS1100/VS1200
The VS 1100 Transceiver thas some unique enhanced features and
comes in two models: 2 IFL and 1 IFL.
The VS1100 2 IFL TRIA has these features:
Completely sealed – no weather cover required
Feed Horn and Ka-Band Transceiver are in line with one
another
Operates with SurfBeam 2 Modem Single COAX connector
Terminator is required
The combined Transmit (TX)/ Receive (RX) connector is
located on the front, right of the TRIA
The used Receive (RX) connector is located on the front left
of the TRIA and is covered with an Technician provided
Terminator
