Plain-language answer: Ice and wet snow add weight and wind area, pull wire geometry downward, change dielectric surroundings, and can enter or freeze around connections.
Why it matters in the complete station
The resulting mechanical load can exceed the antenna’s normal operating load while tuning and pattern shift at the same time.
What to do in the field
Lower temporary systems before accumulation, inspect anchors and supports from a safe distance, and let ice clear naturally—never strike a loaded mast or conductor.
The common mistake
Transmitting through a changed match while ignoring the structural hazard overhead.
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.
