Dtv.gov Maps

Pinpoints the precise Radio Frequency (RF) channel used by local stations. How to Use the DTV Mapping Tool

Navigate to the FCC DTV Reception Maps Portal. Type your address into the location search field or select the "Go To My Location!" prompt. 2. Review the Station List

Channels are graded as Strong, Moderate, Weak, or No Signal.

Do not rely solely on the map. Once an antenna is installed, use the TV’s "Channel Scan" function. If a channel predicted to be strong is missing, the issue is likely local interference or antenna placement, not distance.

And on that edge, there is just silence. No snow. No static. Just the black screen of the digital void.

Users input a specific address, zip code, or city.

Today, the DTV.gov domain is a 404 error. The servers are cold. The maps—those layered PDFs, those interactive Flash viewers (remember Flash?)—are gone. They have been replaced by "DTV Reception Maps" on the FCC’s current site, which are more accurate, more granular, and utterly soulless.

Then came the DTV.gov mandate.

The map assumes a specific antenna height (usually 30 feet for outdoor predictions). If you place an antenna in a basement or on a first-floor window, your reception will be significantly worse than the map predicts.
