Plain-language answer: UV exposure is sunlight-driven degradation of plastics, jackets, coatings, adhesives, and fibers used outdoors.
Why it matters in the complete station
A component can look acceptable while losing flexibility, strength, sealing, or electrical insulation. Products rated for temporary field use may not be intended for permanent sun exposure.
What to do in the field
Check fading, chalking, cracks, brittleness, sticky surfaces, and weakened ties. Replace damaged materials with outdoor-rated parts rather than covering failure with more tape.
The common mistake
Assuming every black cable tie, rope, or coax jacket is UV-stabilized.
Safety boundary
Stop work around power lines, lightning, unstable supports, unsafe wind or ice, damaged components, or uncontrolled public access. Current product guides, component ratings, site rules, electrical code, license conditions, and RF-exposure requirements control the final installation.
