Why it matters in the field
The visually highest point is not always quietest or mechanically safest, and the shortest coax route is not always the best radiation site.
What to do
List the nonnegotiable clearances, survey noise at candidate points, test a temporary deployment, measure tuning, and record on-air results before making it permanent.
The common mistake
Selecting the site from appearance alone without a receive-noise and deployment test.
Current regulations, safety clearances, equipment manuals, exact antenna geometry, and site conditions control. Test the complete installed system at low power before relying on it.
