Explanation
Overview Ultraviolet (UV) radiation from sunlight gradually degrades many plastics, rubber materials, cable jackets, and other non-metallic components used in outdoor antenna installations. Although this process occurs slowly, long-term UV exposure can eventually reduce mechanical strength and weather resistance. Components Commonly Affected Coaxial cable jackets. Cable ties. Plastic insulators. Weatherproofing materials. Protective covers. Signs of UV Damage Cracking. Discoloration. Brittleness. Surface chalking. Loss of flexibility. Reducing UV Damage Use UV-resistant outdoor materials. Inspect components regularly. Replace damaged cable ties and weatherproofing. Protect exposed cables where practical. Applied to Chameleon Products Routine inspection and replacement of weathered components help ensure that Chameleon antenna systems continue providing reliable service throughout many years of outdoor exposure.

The exact result depends on the complete station: frequency, geometry, feed line, matching network, return-current path, environment, operating power, and the reference plane of any measurement. A low SWR establishes an impedance relationship at that point; it does not by itself prove efficiency, radiation pattern, compatibility, or safety.
What to Verify
- Use the newest official product guide or primary service documentation.
- Confirm the exact model, revision, components, configuration, and operating conditions.
- Begin tests at low power and change one variable at a time.
- Do not infer compatibility from connector or thread fit.
