Weatherproofing A8n Series Radio Antenna
6.1.
Introduction
Sealing materials are applied to outdoor antenna connectors to accomplish several
goals. First and foremost is to prevent water from entering the connector. The second
reason is to protect the connector from gradual degradation due to UV radiation
and pollution. Sunlight and weather will oxidize metal surfaces and cause DC
resistance to increase on exposed mating surfaces. It is true that the RF cable
connectors are supposed to be weatherproof, but if left exposed to weather
conditions, they will tarnish and start to look rather ugly in a short time. A good taping
job will also prevent the RF cable connectors from loosening up, which is a common
occurrence for RF cables exposed to vibration and strong winds.
We recommend the following sealing materials for weatherproofing the antenna
connectors:

High-quality, all-weather, black plastic electrical tape, preferably 3/4” (19mm)
wide to make it easier to manipulate the tape around the A8n Series BTS radio
antenna ports. An RF port is often first wrapped with a layer of electrical tape to
make it easier to remove the butyl rubber layer. In addition, one or more layers of
