Dielectric: TV Job at Empire Finished

From the Radio World Who’s Buying What page:
Dielectric has supplied a customized combined TV antenna system to WNYW and WNBC — Channels 5 and 4 in New York — atop the Empire State Building. The system includes main and backup antennas and a signal combining system; it became fully operational in December.
“The main antenna has been installed on the ESB’s well-known spire and the backup antenna has been installed on the building’s ‘mooring mast,’” the supplier stated, referring to the structure designers once thought could be used for debarking passengers from airships.
