What this page is for

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

Small cells and shorter poles frequently never show up in ASR. They are listed here too, labeled as crowdsourced or approximate.
