Waterproof Self-Fusing Silicone Antenna & Coax Tape creates a durable, long-lasting seal for outdoor Meshtastic™ and MeshCore™ antenna connections and RF cable terminations. Use it on N-Type, SMA, and other coax connectors, this tape protects critical joints from water intrusion, corrosion, and environmental damage.

Unlike standard adhesive tapes that dry out, unravel, or fail over time, this self-fusing silicone tape stretches and bonds to itself, forming a seamless, flexible, waterproof barrier without leaving sticky residue. There's no sticky adhesive at all, it seals to itself.

One roll is enough to wrap all external connections on an Atlavox Beacon. 

Key Benefits

• Waterproof sealing: Prevents moisture ingress at antenna and coax connection points.
• Corrosion protection: Shields metal connectors from oxidation.
• Self-fusing silicone: Bonds to itself without adhesives for a permanent seal.
• Outdoor rated: Resistant to UV exposure, weathering, and temperature extremes.
• Flexible & durable: Won’t crack, harden, or loosen over time.

How to Use

1. Ensure the connector and cable are clean and dry.
2. Stretch the tape while wrapping tightly around the connection.
3. Overlap each wrap by approximately 50%.
4. Continue wrapping until fully sealed and allow the tape to self-amalgamate.
