Free Over-the-Air TV
In Charlotte, NC, PBS Kids broadcasts on WUNG, channel 58.2, and WNSC, channel 30.4.

How far the transmitters are, which way they sit, and what that means for the antenna you buy.
The nearest transmitter is 10.9 miles away, and most of the lineup sits within 37 miles.
For Charlotte we would start with an amplified indoor or attic antenna. The towers are far enough out that an amplified indoor antenna, or one mounted in the attic, will pull in far more of the lineup than a basic flat antenna.
