I live in an area where normally I dont have any issues getting live channels except for one, CBS. My antenna has to be pointed in a generally specific way and to do this I fire up the hd homerun app on my mac and move it til the signal strength is acceptable. I would love this feature on the iphone app!
You should try “Signal GH” from the App Store. I use it often.
I too would like to see this feature as the other option is another app I’d just have to pay after already buying this app.
If it does get added in Channels, it could be used for making recording decisions too… especially when there are multiple HD channels with similar programming.
