1.0 GENERAL INFORMATION
1.1 Functional Overview
The VCom TRI1819 is an outdoor RF transceiver for use in broadband wireless systems. The TRI1819 combines a
low noise downconverter, high power upconverter, antenna and high rejection duplexer to offer a fully integrated
solution for 1.9 GHz subscriber terminals. The TRI1819 integrated subscriber transceiver serves to frequency
translate and amplify the upstream and downstream signals to the appropriate intermediate frequencies for use by
the indoor DOCSIS modem. The TRI1819 and antenna are situated outdoors and connected to a cable modem
indoors by a low cost 75 ohm cable (i.e. RG-59, RG-6 or similar). A single RF F-connector on the weatherproofed
enclosure provides the interface to the transmit/receive antenna for rapid installation.

2.0 INSTALLATION
2.1 Unpacking the Unit
Carefully remove the equipment from its packing material and set it on a solid surface, such as a table or desk. If it
appears damaged in any way, notify the carrier, and keep all packing materials for inspection by the carrier’s agent.
2.2 Mounting the Unit
The following hardware is included in the box for mounting the brackets to the pole:
•
1 L-bracket (taped to one of the foam pieces inside the box)
•
1 pole catch
•
1 V-bolt
•
4 #10-32 flange locknuts for connecting L-bracket to cover
•
2 ¼ - 20 flange locknuts for connecting V-bolt and pole catch to the pole
The TRI1819 was designed for mounting on a pole with a diameter of 1.0” to 1.75”. Please ensure that the pole
used is attached securely to the building or other mounting location.
Step 1 – Attach L-Bracket to TRI1819
Before the unit can be attached to the pole, the L-bracket must be attached in the correct orientation according to
the polarization required for the particular customer installation. Diagram 2.2A shows the orientation of the bracket
relative to the cover for both horizontal and vertical polarization.
The active or desired polarization is the one in which the arrow points up. For example, when the TRI1819 is
mounted on the pole, if the arrow pointing up on the back of the TRI1819 says “Horizontal Polarization” then the
horizontal polarization is the active polarization. When the TRI1819 is mounted on the pole, if the arrow pointing up
on the back of the TRI1819 says “Vertical Polarization”, the vertical polarization is the active polarization
Secure the L-bracket to the cover using the #10-32 locknuts.

DIAGRAM 2.2A: LL-BRACKET ORIENTATION
Once the L-bracket is in place, the unit can be mounted to the pole. The pole catch, V-bolt and L-bracket are
oriented as shown in Diagram 2.2B.

STEP 2 – Position V-bolt and pole catch around pole
To attach the TRI1819 to the pole, first position the pole catch over the threads of the V-bolt and hold against the
pole with one hand.

STEP 3 – Position TRI1819 against pole
Using the other hand, bring the TRI1819 up to the pole catch and grab V-bolt, pole catch and L-bracket in a single
hand. Ensure that the pole is inside the “L” of the L-bracket and not on the outside of the L. This is necessary to
maintain antenna alignment during high winds.
STEP 4 – Tighten TRI1819 against pole
Tighten both ¼” locknuts against the L-bracket so that the unit is held against the pole but can still be rotated and
tilted up and down for antenna alignment. The locknut closest to the antenna can be tightened almost all the way
while the back one should be approximately finger tight.

2.3 Connection to the Power Inserter and Cable Modem
Connections to the TRI1819 are made as shown in Diagrams 2.2B and either 2.3A or 2.3B depending on which
power supply and inserter came with the TRI1819.
Please note:
1) Connect the TRI1819 F-Connector to the power inserter, located indoors with the cable modem. The power
inserter is then connected to the Cable Modem, only after the antenna is aligned. The power inserter has
three connections:
DC POWER
Connect to wall adapter with the supplied RG-59 cable with F connectors
TO MODEM
Connect to cable modem (install modem only after the antenna is aligned)
TO TRANSCEIVER Connect to TRI1819
WARNING!
If the power inserter is not correctly connected, the TRI1819 will not operate, and
there is the potential to damage the cable modem.
Ensure that all wires and cables are hooked up before plugging into the AC
adapter/power supply (i.e. hook up to the power supply last).
2) After connection, the F connector must be waterproofed with the supplied rubber sealing tape. See Section 2.4
for details.

2.4 Waterproofing Connections
This will provide moisture protection and keep the connections tight. VCom has provided a 6-inch length of rubber
self-amalgamating sealing tape to use on the TRI1819 F-connector.
Step 1
Use a 6” section of rubber sealing tape. Starting at the TRI1819 end, stretch the tape and wrap it around the
connector as close as possible to the wall of the TRI1819. Overlap the tape by approximately one-half of its width
so that it can form a seal with itself. Extend the wrapping to approximately one-inch past the end of the connector.
Step 2
Cover the sealing tape with electrical tape (not provided). Start approximately one inch further down the cable, and
stretch the tape, overlapping by one-half. Wrap to the TRI1819 end and without breaking the tape, wrap back down
to the cable end.

When done, the connection should be tightly wrapped with tape, with a good seal to the cable.

3.0 ALIGNING THE ANTENNA
3.3.1 Signal Strength and Alignment
When power is first applied an audible signal (beep) will occur. Faster beeping indicates higher signal strength.
Adjust the unit first panning left and right, then up and down until the rate of beeping is maximized. If the unit is
difficult to tilt or turn, loosen the locknuts on the V-bolts slightly.
If the beep rate is very quick, the beeps will continue to be heard for ~3mins and then stop. This quick beep rate
indicates that very little movement is necessary. If the beep rate is slow, the beep will occur for 20 minutes at
minimum signal strength of less than –80 dBm. This slow beep rate indicates that more movement is required.
Once antenna alignment is complete, tighten the locknuts to secure the TRI1819 to the pole.
3.3.2 Resetting the Beeper
To reset the timer for alignment, simply unplug the power supply from its AC connection. Wait 5 seconds, then plug
the power supply back into its AC connection. The beeper will begin beeping as soon as power is available.
