Weatherproof procedures
Cable connections become loose over time due to vibration. Loose connections
let moisture contact and erode the interface to a connector. To avoid
performance problems due to moisture damage, Firetide recommends that you
use butyl mastic and electrical tape or silicone tape to make all outdoor
connections weatherproof.

Best practice:
You can use colored tape for easy identification of the connectors
from the mesh node to the antenna.
Butyl mastic is a synthetic rubber sealant that you can use to make a connection
weatherproof. It is slightly sticky and stays flexible; it bonds to itself to make a
good seal. Butyl mastic and a layer of electrical tape keeps the cable assembly
clean, dry, and easy to change in the future.
Note:
To make a strong watertight connection, keep a high level of tension in the
butyl mastic when you stretch it over the cable and connector.
