2.4 Waterproofing Connections
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 that the connectors be sealed
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 a 6” (15 cm) length of rubber self-amalgamating
sealing tape to use on the outdoor connection of the BTR5857.
Step 1
Use a 6” section of rubber sealing tape. Starting at the BTR5857 end, stretch the tape and wrap it around the
connector as close as possible to the wall of the BTR5857. 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 BTR5857 end and without breaking the tape, wrap back down
to the cable end.
