The VCom TR700B is an UHF Transceiver for use in wireless systems. The TR700B integrates an LNA,
upconverter, power amplifier, RF and IF diplexers to provide a one-box solution for two-way wireless RF
communications. The TR700B and antenna are situated outdoors and connected to a cable modem indoors
by standard RG-59 cable. A single RF connector on the weatherproofed enclosure provides the interface to the
transmit/receive antenna for rapid setup. The Transceiver is configured to work with standard cable modem
frequency plans and levels, permitting direct connection. The Transceiver also includes an RF mute function to
reduce power consumption and broadband noise emissions.
• +24 dBm output for high reverse channel system gain
• Low Phase Noise
• Automatic transmit RF mute (transmits only when an IF signal is present)
• Fully weatherized unit, suitable for outdoor mounting

The following hardware is included in the box for mounting the TR700B to the pole:
• 1 pole catch
• 1 V-bolt
• 2 ¼”x20 flange locknuts for connecting V-bolt and pole catch to the pole
The TR700B was designed for mounting to 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. Simply secure the TR700B unit to a
pole as shown in Figure 2.2A with F-Connector on the bottom.

Included with the TR700B unit is a self-adhesive label for application to the antenna. To operate
the TR700B in compliance with FCC regulations, you must apply the included label to the antenna.
Peel off the protective backing from the label and affix it to the antenna such that the label is
readable from a distance of 5 feet.

Connect the TR700B F-Connector to the power inserter, located indoors with the cable modem. Connect the
power inserter to the Cable Modem. If the TR700B is equipped with the optional self install feature, insure that
the power inserter is connected to the Cable Modem, only after the antenna is aligned.
The power inserter has three connections:
DC POWER Connect to wall adapter with RG-59 cable with F connectors
TO MODEM Connect to cable modem (install modem only after the antenna is aligned)
TO TRANSCEIVER Connect to TR700B
WARNING!
If the power inserter is not connected correctly, the TR700B 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).

Many transceiver problems can be attributed to environmental conditions (including vibration), which can loosen
cables and permit moisture to penetrate the connectors. It is highly recommended to seal the connectors using
a technique similar to the one described below. This will provide moisture protection and keep the connections
tight. For your convenience, VCom has provided two 6 inch lengths of rubber self-amalgamating sealing tape
to use on the two connections of the TR700B. The diagrams below show the N connector, but the F connector
also should be sealed using the same technique.
STEP 1
Use one 6” section of rubber sealing tape. Starting at the TR700B end, stretch the tape and wrap it around the
connector as close as possible to the wall of the TR700B. Overlap the tape by approximately one-half of it’s
width so that it can form a seal with itself. Extend the wrapping to approximately one inch past the end of the
connector.
DIAGRAM 2.5A: WATERPROOFING CONNECTION – STEP 1
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 TR700B end and without breaking the tape, wrap
back down to the cable end.
