Alaska isn’t known to have many tall structures, but one notable one was the LORAN-C transmitter, Port Clarence. However, this structure was demolished on April 28, 2010, even though it stood at 1,350 feet. So, what is the tallest structure in Alaska now? 

Continue reading and discover Alaska’s tallest structure, seemingly a ladder to the clouds. Previously, the tallest structure in Alaska was the LORAN-C transmitter, Port Clarence. Still, the Knik TV Mast has now replaced it.

Why Did They Demolish the Port Clarence LORAN-C Transmitter?

LORAN-C is a radio navigation system that uses low frequencies to send radio signals to another system. Initially, it was designed to be used by coast guards to communicate between boats. This was mainly used in 1970 and the 1980s. 

Until 2010, LORAN-C broadcast signals to communicate between coast guards. However, on February 8, 2010, President Obama declared the system obsolete and terminated the use of them in the United States. Due to this, the LORAN-C transmitter Port Clarence was demolished as newer technology would soon replace the broadcast signals, such as GPS systems.

After the demolition of the LORAN-C transmitter Pork Clarence, the next tallest structure became the Knik TV Mast. The structure is a TV guyed mast used by FM radio and television broadcasting. A guyed mast is a tall and thin vertical structure that uses guy lines to help support it.

The Knik TV Mast uses diagonal tensioned cables attached to the ground to help keep the structure from moving. Guyed masts are mainly used for radio towers that use antennas or function as massive radiator antennae. However, the company that owns the structure is Alaska Public Telecommunications, Inc. It stands at a height of 808 feet, equivalent to 246 meters.

Knik TV Mast Television

The TV mast broadcasts four programs: KAUU, KAK, KTUU-TV, and KYUR. KAUU is a television station that broadcasts in Anchorage, AK. It’s affiliated with CBS and is owned by Gray Television and NBC. KAKM, also known as virtual channel 7, is a PBS TV station licensed in Anchorage, AK. It is owned by Alaska Public Media and National Public Radio (NPR).

On the other hand, KTUU-TV is also a TV station in Anchorage, AK. Gray Television and CBS own the TV station. The last station the TV mast broadcasts is KYUR, virtual channel 13, affiliated with ABC and CW+. It’s located in Anchorage, AK, and Vision Alaska LLC owns it.

Knik TV Mast FM Radio

Two radio station programs are broadcast from the TV Mast, including KNBA and KSKA. KNBA is a radio station in Anchorage, AK, owned by Koahnic Broadcast Corporation. It’s an alternative music format program. On either hand, KSKA is a radio station in Anchorage, AK, that is a non-commercial station. It broadcasts NPS network and BBC World Service information.

The tallest structure is the KRDK-TV Tower, located in North Dakota. It sits at 2,060 feet and is the tallest structure in the United States. Previously, the KYLY-TV tower used to be the tallest in the world, but similar to the LORAN-C transmitter, it was changed. An antenna was removed from the KVLY-TV tower, which brought the total height from 2,063 feet to 1,987 feet, making KRDK-TV tower the new tallest structure.
