Why it matters in the complete station
Water follows cable jackets and can migrate into coax, connectors, walls, or equipment. The loop works with—not instead of—weather sealing and a suitable entry path.
What to do in the field
Place the low point below the entry or connector, avoid a bend tighter than the cable allows, secure the cable, and inspect after storms.
The common mistake
Pointing a connector upward and expecting tape alone to stop water indefinitely.
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.
