The Armstrong Tower, also known as Alpine Tower, is a distinctive 129.5 meter (425 foot) tall lattice tower featuring three large cross-arms, located atop the Alpine, New Jersey palisades overlooking the Hudson River a few kilometers north of New York City at 40°57'39.0" N and 73°55'21.0" W (40.9607 -73.9225). It is owned by Alpine Tower Company and managed by CSC Management, LLC,[1] both owned by Charles E. Sackermann, Jr.[2]
The tower is the permanent transmitter site for locally based experimental station WA2XMN and Fairleigh Dickinson University's educational FM station WFDU, in additional to numerous directional radio services (including as a cell site). It is clearly visible from across the Hudson River and is used as a Visual flight rules waypoint[3] by aircraft flying within the New York City Special flight rules area.[4]
The tower was originally constructed by inventor Edwin Howard Armstrong in 1938 for developmental activities that led to modern FM radio. The original transmissions (W2XMN) occurred at 42.8 MHz.[5][6] At the tower base is a building originally used for research by Armstrong, which still has the W2XMN call sign engraved above its main entrance. This building currently houses the Armstrong Field Laboratory, and serves as a museum containing artifacts from the development of FM radio technology.[7]
The structure was also used as a temporary transmitter site for some of New York City's television stations after the collapse of the World Trade Center, including its transmitting antenna, following the September 11, 2001 attacks.[8][9]
