OTAMap is a comprehensive tool that assists in locating and pointing antennas towards Over The Air (OTA) television and FM stations. Covering the continental USA, Alaska, Canada, Hawaii, Northern Mexico, and some US territories, OTAMap provides up-to-date information on available OTA channels within a 150-mile radius based on your current geographical position. The app displays the positions of transmission towers relative to your location, aiding in adjusting HD OTA antennas for optimal reception, even for distant stations.

In its latest 2.0 version, OTAMap introduces several new features. Users can now select between FM or TV stations, filter station lists by various criteria, sort displayed stations, save and recall locations, and download the latest FCC station data. The app is no longer server-based, offering offline functionality for certain features. Additionally, enhancements like fixed magnetic declination, Super Contour Map, search by call sign, and support for the Great White North have been added.
