" digital signals are either there, or they're not." Well, yes and no. *All* signals are analog (even your "digital media" like a hard disk). Internally, what is sensed directly by the electronics is analog. We then convert the signal to digital ... for example we might sense "+3.4 volts" ... in a "5v circuit" that's going to read as a "1". 2.4v will read as a zero. The tricky cases are between 2.4 and 2.5v, especially if it is moving up and down rapidly .... the *result* is going to a "zero or a one" which in the aggregate is going to result in your having a picture (sharp) or nothing ... rather than a fuzzy picture. (and yes, I know antennas aren't going to be simply measuring voltage ...).
Whether you can get good signals inside your home will depend a lot on 1. Where the transmitter is 2. What's between you and the transmitter 3. What your walls are made of (metal? plaster?? drywall???) 4. What (if anything) in your house generates noise in those frequencies (think big electric motors, for example). it may be that you can get good results with careful placement, or you might not have a prayer. Even outdoor antennas aren't necessarily effective, or are effective only if/when pointed at the specific transmitter (really good antennas get around that by actually being a constellation of antennas internally ;>...your phone for example ;> ). Consumer grade antennas hardly ever provide any useful feedback, a few TV's do provide signal strength diagnostics (I haven't seen any with appropriate assistive support :<).
