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.



  • Wow

    By BrianGGG
    Super helpful. I went searching for a way to help me position my antenna. This was exactly what I needed.

    This made aligning my antenna so easy. I was able to see exactly what was happening on both tuners (picking up from 2 different towers) in real time. Well done.

    This is a great app for adjusting my Antenna array. Connected to a HDHomerun I am able to see real time differences in channel strength as I adjust my antenna components.
  • So useful

    By Voltron4lyfe
    I was having problems figuring out which way to point my antenna. Using this I easily figured out the best spot to put my antenna. A change of 30 degrees made al the difference and I now have clear, uninterrupted signal. Saved me so much time and frustration.

    This product was purchased by mistake. I do not have the equipment to use it with.

    Wow.. awesome app! Glad I found this it will help with tuning my ant setup
  • I cannot recommend this enough!!!

    By ccecil
    This app does exactly what I want it to do!! I have several local channels that I can get easily, but getting those channels 60 miles away required much trial and error- measuring signal strengths in different channels and different antennas- inches can make a difference. This is one of the most useful apps I have purchased. If your setup is complex, stop wasting your time. You need the right tool and this is it.
  • Best $2.99 I ever spent

    If you have an HD Homerun tuner, this app will help you point your antenna. The ability to view signal strength and quality for 2 channels simultaneously is genius.
  • Great app

    Great app to show the signal strength from my HDHR. The antenna location map using the built in compass was an added plus too.
