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

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.
