I am curious. Having always lived in rural areas, I only have ever had CBS, ABC, and PBS over the air. Where I am currently at it is PBS only. How many channels OTA do some get if six tuners could ever be needed? Isn't only the historic big four, the CW, and PBS that broadcasts OTA? I guess that is six, but what are the odds something would be on the same channels at the same time that you wanted to watch?
