Water Proofing Antenna Connections
Waterproof all outdoor coax connectors using a three layer sealing process of initial
layer of adhesive PVC tape, followed by a second layer of self-vulcanizing
weatherproofing tape such as 3M 23 (order # 1000-2314), with a final layer of adhesive
PVC tape (see Figure 2-9).
2.6.4.5
System Grounding
Direct grounding of the OLCT 200 enclosure via a good electrical connection to a well-
designed grounding system is essential. This will protect your system, reduce the
damage that can occur during lightning strikes and reduce noise.
