That's the way it works with digital. Either you get all the bits and the picture is great, or you don't get them. Sometimes, if you're on the "hairy edge", you'll get a picture with frequent pixelation and dropouts.
The signal meter measures received quality, i.e., how easy a time the receiver is having telling a 1 from a 0 in the received signal. For satellite reception, about the only thing that causes a low quality signal is low signal strength, so the vendors called this a "signal strength" meter. This term is also understood by non-technical consumers.
For OTA, the equipment manufacturers kept the same term, even though low signal level is only one thing that can cause a low signal quality. Bad multipath, i.e., reflections from surrounding objects of the type that causes ghosting on analog signals, is also a major cause of a low meter reading.
A TV signal level meter can measure signal level. TV antenna installers (good ones, anyway) have such equipment. In any case, I wouldn't signal level would be a problem in the West Hills, unless maybe we're talking about an indoor antenna in a basement.
