App Description

Signal GH is a tool for users of the HDHomerun networked digital TV tuner who want to monitor and improve their Over The Air (OTA) reception quality. It graphs the signal quality from multiple channels simultaneously, allowing the user to more rapidly adjust and upgrade the OTA receiving hardware for his home, i.e., cables, connections, splitters, pre-amps, and antennas. The graph can be mirrored to a TV via Airplay and an AppleTV.

United States users also have the benefit of a map of digital television broadcasting towers. Depends on the accuracy of your device's compass.

If you don't have an HDHomerun, you don't need this product. If you do have an HDHomerun, and use it for over the air reception, you will likely find it useful.

If the automatic scan does not find a station you expect, add the station's real channel to the list of active channels via the Channels subview of the Settings tab.

Signal GH does not support QAM (digital cable) Please make sure your HDHomerun is set to use a broadcasting channel set and not a cable channel set.

You cannot use this software to watch video on your iOS device. This is a diagnostic tool.
