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.

United States users also have the benefit of a map of digital television broadcasting towers. Remember the device compass is not particularly accurate.

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.

Signal GH does not support QAM (digital cable) nor would it make any sense to support QAM. If you are using your HDHomerun solely with digital cable, please do not make the mistake of downloading this app.

You cannot use this software to watch video on your iPhone or iPod Touch. This is primarily a diagnostic tool.
