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.

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!

Lost without it

I have a less than ideal antenna location with lots of trees and neighbors. I was totally guessing before I added this app with a HDHomeRun. Because of location challenges, I have to tweak the alignment once in a while. This app gives me the signal and quality readings for my best alignment. A must have. Many thanks to the developer.

Thank you. I get motivated by stories like this. Have a good TV watching season.

Feature request

The app works very well for checking the signal coming from the antenna for processing. It would be great if you could change the refresh rate when doing this though. That would eliminate the slight lag in seeing the effect of the antenna position change.

Developer Response ,

I’d be open to upping the frequency of polling. The one second polling I’m doing now was arbitrary, and devices/networks were much smaller when I chose that value, so I’ll look into it.
