Sealing the Cable Connectors
Most problems associated with wireless outdoor installations are related to
degrading performance due to the effects of corrosion of the antenna cable and
cable connectors. To avoid this type of problems, you must always seal the
cable connectors that are located outdoors using the weather proofing tape
provided.
You are advised to seal the connectors only after you have verified optimal
alignment of the antennas using the Wireless Link Test as described in the
"Avaya Wireless OR Manager - User’s Guide". Doing so will enable you to adjust
antenna placement and cable routing without removing the tape.
1. Prepare the cable and connectors so that they are free from dust, dirt and
grease.
2. Attach the tip of the weather proofing tape to the cable just above the
connector.
3. Holding the tape in its position, now stretch the tape and wind it half-lapped
around the cable and connectors to form a void-free joint.
The degree of stretch may vary in different sections of the joint, as long as
the overlaps accomplish a void-free application.
To protect the weather-proofing stretch tape from the effects of Ultra-Violet (UV)
radiation (for example from direct sun-light), you should protect the joint with two
half-lapped layers of any vinyl plastic electrical tape. Alternatively, you can apply
silicone sealer to protect the weather-proofing tape from sunlight, rain and other
weather conditions.
