I used TVFool in the past to setup my current antenna. This post and comment thread led me down the rabbit hole again though as one of my VHF stations has always been a bit flakey and when the wind blows UHF is an issue.

I learned about the difference between UHF and VHF and how vegetation is likely making my UHF channels bumpy when the wind howls. The VHF is likely just an aiming issue.

Anyway, one thing I’ve always looked for is a reliable way to see how changes in alignment affect the signal in real-time. I discovered Signal GH an app that will connect to your HDHomerun device and provide signal statistics.

Just thought this might be useful for anyone attempting to fine tune their setup.
