1.0 GENERAL INFORMATION
1.1 Functional Overview
The Vecima Networks TRI2525B is an outdoor RF transceiver for use in broadband wireless systems.
The TRI2525B combines a low noise downconverter, high power upconverter, antenna and high
rejection duplexer to offer a fully integrated solution for 3.5 GHz subscriber terminals. The TRI2525B
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 TRI2525B 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.
1.2 Module Features
•High Output Power: Up to +39 dBm EIRP with QPSK
•Automatic transmit RF mute when modem is not transmitting
•Low Noise: < 7 dB typical
•Temperature compensation to guarantee specifications over full operating temperature range
•All local oscillators are frequency synthesized and locked to a common internal high stability reference
•Integrated planar antenna (15°beamwidth, 18 dBi gain)
•High reliability, state-of-the-art design using microstrip, MMIC and surface mount technology
•Conservative component derating and 100% burn in help ensure reliable operation
•Fully weatherized unit, suitable for outdoor mounting
•Audible installation alignment beeper; to facilitate customer self install

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 TRI2525B 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 TRI2525B
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
TRI2525B is mounted on the pole, if the arrow pointing up on the back of the TRI2525B says “Horizontal
Polarization” then the horizontal polarization is the active polarization. When the TRI2525B is mounted
on the pole, if the arrow pointing up on the back of the TRI2525B 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:L-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.
