This photo shows the main support steel for the broadcast mast atop the Empire State Building. This is located just below the base of the mast, on what would be the 104th floor. Just to the left you can see the steel ladder that connects to the platform at the base of the mast. No workers are allowed outside when all the antennas are energized, due to the very high RF field present.
