Over-the-Horizon Backscatter Radar Network, Columbia Falls Radar Site Receive Sector One Communications Antennas, At the end of Shadagee Ridge Road, Columbia Falls, Washington County, ME
Summary
Significance: The Over-the-Horizon Backscatter radar network was an important physical and scientific product of the Cold War. From theories that had been conceived in the days of early long-distance radio transmissions, and building on over three decades of research into the subject, the network was a tremendous technological and military accomplishment. Although it was only starting operation as the Cold War was ending, the ability of a radar system to warn against low-flying aircraft at distances of up to 1,800 miles away was an amazing step forward in air defense. These two structures are tropospheric scatter communications antennas that transmit signals received by the three receiver arrays to the Bangor operations center for analysis
