KOAC (550 AM) is a non-commercial radio station licensed to Corvallis, Oregon, United States. The station is owned by Oregon Public Broadcasting, and airs OPB's news and talk programming, consisting of public radio shows from NPR, American Public Media and the Public Radio Exchange, as well as locally produced offerings. It is operated from OPB's studios and offices on South Macadam Avenue in Portland.
The transmitter is located off of NE Granger Avenue near U.S. Route 20 in Albany. Due to its transmitter power and location near the bottom of the AM dial, its daytime signal provides at least secondary coverage from Portland to Roseburg. It is the only directional AM radio station in the United States which uses a shunt-fed antenna.
