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.
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. VCom Inc. TRI1819 Manual; ml_tri1819_02(Feb 2005) Approved: C.H.
DIAGRAM 2.2B: TRI1819 MOUNTED TO POLE Vertical Alignment Horizontal Alignment 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. VCom Inc. TRI1819 Manual; ml_tri1819_02(Feb 2005) Approved: C.H.
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.
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.

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.
When done, the connection should be tightly wrapped with tape, with a good seal to the cable. VCom Inc. TRI1819 Manual; ml_tri1819_02(Feb 2005) Approved: C.H.
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.
