Armstrong Tower, Radio tower in Alpine, New Jersey, United States
Armstrong Tower rises 425 feet high with three steel arms extending from its lattice structure overlooking the Hudson River from the Palisades.
Edwin Howard Armstrong constructed this transmission tower in 1938 to broadcast experimental FM radio signals under the call sign W2XMN at 42.8 MHz.
The base building contains the Armstrong Field Laboratory museum, displaying the technological evolution of FM radio broadcasting in the United States.
The tower transmits signals for Fairleigh Dickinson University's FM station WFDU and functions as a visual waypoint for aircraft in New York City airspace.
Following the September 11 attacks, this tower provided temporary transmission capabilities for New York City television stations after World Trade Center loss.
