We offer several resources here relating to over-the-air (OTA) broadcast services (TV, FM, and others). We have a variety of online tools, downloadable content, reference information, and discussion forums to help users learn, understand, and make informed decisions about the OTA services available to them.

The Signal Analysis Tool lets you enter a location by address or by coordinate, and optionally the height of an antenna above ground. It then runs 3D propagation models for the exact location and height and generates a "radar plot" report that summarizes the signal strength and direction of all the channels in the area.
