It is clearly visible from across the Hudson River and is used as a Visual flight rules waypoint by aircraft flying within the New York City Special flight rules area.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. 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.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, during the September 11, 2001 attacks.

The Palisades, also called the New Jersey Palisades or the Hudson River Palisades, are a line of steep cliffs along the west side of the lower Hudson River in Northeastern New Jersey and Southeastern New York in the United States. The cliffs stretch north from Jersey City about 20 miles (32 km) to near Nyack, New York, and visible at Haverstraw, New York. They rise nearly vertically from near the edge of the river, and are about 300 feet (90 m) high at Weehawken, increasing gradually to 540 feet (160 m) high near their northern terminus. North of Fort Lee, the Palisades are part of Palisades Interstate Park and are a National Natural Landmark.The Palisades are among the most dramatic geologic features in the vicinity of New York City, forming a canyon of the Hudson north of the George Washington Bridge, as well as providing a vista of the Manhattan skyline. They sit in the Newark Basin, a rift basin located mostly in New Jersey. Palisade is derived from the same root as the word pole, ultimately from the Latin word palus, meaning stake. A "palisade" is, in general, a defensive fence or wall made up of wooden stakes or tree trunks. The Lenape called the cliffs "rocks that look like rows of trees", a phrase that became "Weehawken", the name of a town in New Jersey that sits at the top of the cliffs across from Midtown Manhattan.
