Protecting Cables and Connections Avoiding Hazards

On a module with an external antenna, use accepted industry practices to wrap the connector to
prevent water ingress. Although the male and female N-type connectors form a gas-tight seal with
each other, the point where the cable enters each connector can allow water ingress and eventual
corrosion. Wrapping and sealing is critical to long-term reliability of the connection.
Possible sources of material to seal that point include
• the antenna manufacturer (material may have been provided in the package with the antenna).
• Universal Electronics (whose web site is http://www.coaxseal.com
), who markets a weather-
tight wrap named Coax-Seal.
Perform the following steps to wrap the cable.
Procedure 4: Wrapping the cable
1. Start the wrap on the cable 0.5 to 2 inches (about 1.5 to 5 cm) from the
connection.
2. Wrap the cable to a point 0.5 to 2 inches (about 1.5 to 5 cm) above the
connection.
3. Squeeze the wrap to compress and remove any trapped air.
4. Wrap premium vinyl electrical tape over the first wrap where desired for abrasion
resistance or appearance.
5. Tie the cable to minimize sway from wind.
