The farthest main network tower for Altadena is KLCS (PBS), 4.6 miles away with a strong estimated signal. That is why we suggest an indoor antenna here. Viewers who do not need that station can often manage with less.

KWHY-TV is only 4.3 miles away with a strong signal. Signals that strong can overload an amplifier, so start without one and add it only if distant channels are missing. Read when an amplifier helps.
