Clicking on any station's call sign pulls up detailed data, showing the compass direction (heading) from your home to the transmitter. Use this information to point a directional antenna directly at the towers for optimal signal capture. 💡 How to Use DTV Maps to Pick the Right Antenna
If the map shows that all local broadcast towers are clustered in one direction, a high-gain directional antenna is best. If towers are scattered in different directions, an omnidirectional antenna or an antenna rotor is necessary. dtv gov maps
Check the RF channel number (not the virtual channel on your TV). If some of your favorite local stations transmit on RF channels 2 through 13, you need an antenna with VHF capabilities . If they are 14 or higher, a UHF-capable antenna works. Clicking on any station's call sign pulls up
The is the most reliable government resource for finding free, over-the-air (OTA) digital television signals available at your specific location. If towers are scattered in different directions, an
The tool divides local stations into four distinct, color-coded tiers based on their predicted signal level: Signal Tier Color Indicator Recommended Antenna Type Indoor antenna or small tabletop model usually suffices. Moderate Attics or amplified indoor antennas are recommended. Weak Large, directional outdoor antenna mounted high up. No Signal Signals are obstructed by terrain or are too far away. 3. Note the Antenna Direction (Heading)
Predictions assume an outdoor antenna mounted 30 feet above the ground . If you use an indoor antenna or have it placed lower, your real-world signal strength might be weaker.
