The mapping tool became a primary resource for the public. It was promoted by major TV networks and news outlets. For instance, directed viewers to www.dtv.gov/maps for "the FCC's online digital reception mapping tool," which also provided information on "proper antenna selection and installation and re-scanning procedures to maximize your ability to receive digital television signals". The Seattle Times also recommended the tool to its readers in a dedicated Q&A about the DTV switch. This widespread promotion cemented "DTV Gov Maps" as the go-to authority for reception information.

The FCC categorizes signal strength into four main colors/ratings. Understanding these is crucial for selecting an antenna.

| Color | Signal Strength Category | Meaning for the User | | :--- | :--- | :--- | | | Strong | The signal is robust. A cheap indoor "rabbit ear" antenna or a flat panel should generally work. | | 🟡 Yellow | Moderate | Reception is likely but may require a higher-quality indoor antenna placed in a window. | | 🟤 Tan | Weak | A standard indoor antenna will likely fail. An outdoor or attic-mounted antenna with a pre-amplifier is often required. | | 🔴 Red | No Signal | Reliable reception is highly unlikely due to distance, terrain, or low station power. |

Beyond consumer use, the data was crucial for broadcasters, antenna manufacturers, and policymakers. The CSV files of prediction data for every zip code were made available for technical analysis and business planning.
