20 of them are within 25 miles of SeaTac, 2 sit 25 to 45 miles away and 0 are more than 45 miles out. Four of the 8 network stations in range are licensed to Seattle, so most of the network channels you will find here come from Seattle's stations.

All of the main network towers are within their radio horizon as seen from SeaTac, so signals arrive fairly directly and a well-placed antenna should hold them steadily.

The farthest main network tower for SeaTac is KCPQ (Fox), 25 miles away with a fair estimated signal. That is why we suggest an amplified indoor or attic antenna here. Viewers who do not need that station can often manage with less.

KFFV is only 12 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.

With 21 stations at fair strength or better, SeaTac ranks 5th of 398 places in Washington: more than the typical Washington town (17). Its nearest major network tower is 12 miles away, against a state median of 19 miles.
