DTV Reception Maps

To help you find free over-the-air channels, the tool provided by the Federal Communications Commission (FCC) is the authoritative resource.

Contours vs. heatmaps: Contours show discrete service boundaries (e.g., 41 dBu contour). Heatmaps show gradations of predicted signal strength.
Thresholds: Different services and use-cases use different thresholds (e.g., 36 or 41 dBu for UHF analog-era benchmarks; digital TV often uses dBu thresholds tied to a given receiver/antenna performance).
Reliability: Maps show predicted conditions under standardized assumptions (receiver antenna type, percentage of time coverage, etc.). They are not guarantees of real-world indoor reception.
Interference areas: Regions where signals from multiple transmitters are predicted to conflict or where protection is offered to certain licensees.
Population metrics: Be cautious—population served is typically an estimate based on census counts inside the contour and assumes uniform distribution within census units.

UHF channels (14–51): These signals behave more like light; they are easily blocked by hills and buildings but are generally easier to capture with compact antennas.
VHF channels (2–13): These signals are larger waves that can bend slightly around hills, but they require larger antenna elements.
