While our antennas might be weatherproof - It's critical that the connections on outdoor antennas and fittings are properly sealed. Water will seep into the tiniest crack (such as an exposed screw thread) and slowly degrade electrical performance over time.
Normal electrical tape will not prevent water ingress. Instead, use silicone rubber self-amalgamating tape to seal external connections.
- Work in dry conditions, so no moisture is trapped under the tape.
- Remove the paper backing from the tape.
- Wrap the antenna connection starting at least 5cm below, and finishing at least 5cm above, keeping the tape stretched and under tension as you wrap.
- Tension the tape while wrapping so it is stretched to about double the original length.
- Overlap the wrap by at least 50%.
- Allow the tape to cure for several hours in a dry environment.
Stretching the tape as you wrap activates the rubber material, and it will join to itself and shrink slightly, producing a watertight boot that will last many years. This is an invaluable investment to avoid having to go back up the ladder to troubleshoot a faulty antenna installation.
