US infrastructure, mapped from public records
Two federal registers, made readable. Every antenna structure the FCC requires to be registered, and every charging location reported to the Alternative Fuels Data Center — with the rankings, distances and densities that the raw files leave you to work out yourself.
What is in here
Underlying data last retrieved 28 Aug 2026. Both registers update on their own schedules; see data sources.
Antenna structures
EV charging
Charging locations with port counts, connector types and network coverage. The DC fast share is the number that decides whether a place works for travel or only for parking.
| State | Locations | DC fast |
|---|---|---|
| California | 20,987 | 24.0% |
| New York | 5,780 | 14.8% |
| Massachusetts | 4,756 | 15.5% |
| Florida | 4,692 | 30.7% |
| Texas | 3,988 | 38.9% |
| Washington | 3,372 | 23.1% |

if you are trying to work out what the data means- What the tower database misses, and why your neighbourhood looks empty
The FCC register covers structures needing registration — roughly those over 200 feet. Small cells, rooftops and indoor systems are absent. If you searched your address and found nothing, this explains why.
- Why your signal is bad — seven reasons that have nothing to do with the nearest tower
Distance to the nearest mast is a small part of why mobile coverage fails. Here is what actually determines whether you get bars, and why the tower two streets away may not be helping you.
- EV charging levels 1, 2 and 3 — what the numbers actually mean
The three charging tiers, realistic charging times for each, and why the fastest number on a charger's label is almost never the speed you get. Practical rather than promotional.
What this site will not tell you
The FCC Antenna Structure Registration database covers structures that require registration — generally those over 200 feet or near airports. Many small cells, rooftop antennas and short towers are not registered and will not appear here.
"Owner" is the entity that registered the structure, usually a tower company such as American Tower or Crown Castle. It does not indicate which carriers operate equipment on the structure.
Coverage figures here are geometric estimates from structure height, labelled as such wherever they appear. Charging port counts are configured capacity as reported, not live availability. The methodology page sets out every calculation.
