VLF Transmitter Cutler, Military radio station in Cutler, United States.
The VLF Transmitter Cutler is a military radio station in Maine with two identical antenna systems supported by central masts reaching 304 meters high, surrounded by twelve supporting towers arranged in concentric rings. The facility operates at 24 kHz with a maximum output of 1800 kW, designed so that one antenna can be maintained while the other continues transmitting.
This station began operations in January 1961 and was one of the world's largest longwave transmitters at that time. It was built specifically to reliably communicate with submarines in the North Atlantic.
This facility marks a turning point in how the military could communicate with submarines anywhere in the world. Visitors today can understand the importance this technology held for naval operations.
The facility sits on a large site in rural Maine and requires planning before a visit. The grounds are expansive, so it helps to check ahead which areas are accessible and how to get around best.
The antenna system includes an electrical heating mechanism for de-icing that operates through an extensive network of copper ground wires. This engineering solution prevents ice buildup on the structures from disrupting signal transmission.
