Start here: Skin effect is the tendency for alternating current density to concentrate nearer a conductor’s surface as frequency rises.
Why this changes a real station
It reduces the effective conducting cross-section and increases AC resistance; material conductivity, permeability, frequency, plating, and surface condition matter.
What it looks like in practice
At HF, connector and conductor surface quality can matter more than a DC continuity check suggests.
What to do next
Use RF loss data for the actual material and geometry instead of extrapolating from DC resistance alone.
Evidence boundary
Keep frequency, reference plane, antenna geometry, losses, measurement method, and safety conditions attached to the conclusion. A match, a DC check, or one field symptom does not prove efficiency or identify the complete RF path.
