re: Questions about using a digital antenna in BR

You'll get up to 22 channels with an indoor antenna depending on where in the city you're located. Most of the stations have not just their main channel but 2 or 3 additional channels they broadcast on, e.g., 27-1, 27-2, 27-3, 27-4. There is no such thing as a "digital" antenna. I've gotten satisfactory results with just a plain old-fashioned rabbit ears.
