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.

I used this app, an HDHonerun quad tuner I already had and another great piece of software from this developer (TV Towers U.S.A.) to install an antenna at my dad’s house, and it turned what used to be a long game of “point and guess” into a quick, simple and painless task. (More than that, it actually made it kind of fun!) The Towers app made it easy to know where to point the antenna, while the SignalGH app let me see the strength of the signals I was receiving in real time on my phone without having to run up and down the ladder. Because my HDHomerun device had four tuners, I could dial into four different stations at the same time and see how moving towards one station affected the signal I received from the others. Once we completed things and did a Channel scan, we picked up everything we were expecting and a few more. I didn’t have to re-climb the ladder and adjust the antenna once. If you have an HDHomerun, using these two apps together will greatly simplify your antenna installation process, especially if you’re doing it by yourself. I highly recommend them both. Thanks for making these great apps. Job well done!
I’m honestly surprised in the number of bad reviews from people who can’t read and don’t understand that this is an app for the HDHomerun line of equipment.
That said, if you know what this app is and what it is for, it is an invaluable tool for anyone setting up an OTA system with at least one HDHomerun device. Having live feedback of antenna positioning including all the transmitter data, compass directions, etc will ensure you get the best signal your equipment can handle.
I especially love the ability to compare multiple tuners and channels on the fly to see how a position may improve one channel but degrade another.

Invaluable for cord cutters
I’ve been troubleshooting issues for months with my HDHomeRun Duo and Plex Live TV. Plex would disconnect and complain about a weak signal, but I had no indication of the actual signal strength at the HDHomeRun box.
I purchased Signal GH, and immediately determined my signal strength was lousy. I used it to systematically troubleshoot my antenna installation, and discovered the transformer on my external antenna had a broken lead. Replaced the transformer, and Signal GH confirmed my signal strength was excellent, and the antenna was pointed correctly.
I use Signal GH anytime Plex hiccups so I can rule out signal strength. Invaluable app!
