RCA Signal Finder app for iPhone and Android
Take the tower finder outside. The app uses your phone's GPS and compass to show where every nearby TV tower is, so you can point your antenna while you are standing right next to it.
What the app does
- Finds the towers around you. The same 6,983 licensed U.S. TV transmitters as this website, with network, virtual channel and distance.
- Points you at them. Pick a station and the phone's compass shows which way to turn until you are facing the tower.
- Estimates signal strength. Each station gets an estimated signal level so you know which channels are realistic before you scan.
- Recommends an antenna. It tells you whether an indoor, amplified, outdoor or long-range antenna suits your spot.
Using it to aim your antenna
- Open the app next to your antenna and allow location access.
- Choose the farthest station you want to watch.
- Hold the phone flat, away from metal, and turn until the app shows you are facing the tower.
- Point the antenna the same way, run a channel scan on your TV, and fine-tune a few degrees at a time.
Full details are in the guide on how to aim a TV antenna.
App or website?
Use the website finder to research from a computer: compare cities, look up channel numbers, read the antenna advice. Use the app on the roof, in the attic or at the window, where you need the compass in your hand.
