If your home is conventional wood frame construction with no foil faced insulation or metal siding, the RCA ANT-121 should do quite well for you. That you see a couple of analog signals now, indicates you will likely be able to see digital signals once you connect and configure a digital ATSC over-the-air tuner. (Digital cable uses a different format, QAM. Be sure to set your tuner for ATSC, Antenna, OTA or Air... how ever the vendor labels it in the set-up menu.)
Coco is right, your analog tuners can't decode the new digital format broadcast signals.
