Weatherproofing Connections Weatherproofing your antenna and/or cable connections on your outdoor AP is essential to reliability and longevity of your product. This process prevents water from entering the AP or antennas through the connectors. A good weatherproofing job consists of three wrappings: 1. electrical tape 2. butyl rubber 3. electrical tape The first wrapping of tape should be at least two layers, followed by a single wrap of butyl rubber, and four-layer wrap of electrical tape. This provides good protection from water, heat, and other potential hazards that could damage your AP or antennas. Additionally, wrap your connections such that water is always directed down and away from connections.
