Each route should justify itself as a useful lookup page, not just another filter state.

Weak signal?

Tower distance is the first thing to check

People looking up towers near a home or office are often diagnosing weak signal. Distance to the nearest site explains most of it; terrain and building materials do the rest.

Distance drives signal strength

Precision note

Not every nearby site has an FCC structure match
