High Island (Bronx)


High Island is a small, uninhabited, privately-owned island, part of the Pelham Islands in the Bronx, New York City. It lies east of the north end of City Island between City Island Harbor and Pelham Bay in Long Island Sound. It is connected to City Island by a sandbar that emerges at very low tide, as well as by a small private bridge.
Previously used as a stone quarry and then a summer resort, the island today is used to support two radio station transmitters and antennas.

History

High Island was once known as Shark Island due to the many sand sharks which used to swim in the nearby waters of Pelham Bay. The island is comparatively high with a shape similar to a gumdrop, thus alluding to the origin of its present-day name.
Elisha King purchased the island in 1829 to quarry stones.
During the 1920s the Miller family operated a community of summer rental cottages catering to about 40 families. In 1961, it was purchased to use for radio transmission towers.

Current use

, the entire island and two transmitters are owned by Entercom. It houses the transmitters and antenna towers for WCBS and WFAN, both of which are owned by Entercom. Previously, the WCBS facility was located on nearby Columbia Island in Westchester County, New York.
On August 27, 1967, a small private airplane crashed into the radio tower, destroying the antenna and taking WCBS and WNBC off the air, the day before WCBS's all news format launched. Both stations were able to borrow nearby transmission facilities for about a week, until an emergency tower could be erected on High Island. The permanent replacement was built with a second tower as an emergency backup.
The taller of the towers is. The shorter tower is and was built in 2001 to replace the emergency tower erected in 1967. The proximity of these two AM radio stations has, at times, caused interference on telephones and electronic equipment on nearby City Island. High Island is only an AM radio transmission facility. It does not have any studios or tower tenants, other than the two AM radio stations. Both WCBS-AM and WFAN-AM broadcast from studios located at the Hudson Square Broadcast Center in Manhattan.
The island is currently uninhabited. A full-time caretaker's residence was in use from 1961 to 2007. The island is currently maintained by the radio stations' engineers and contractors. Advances in broadcast and security technology have made remote monitoring of both the radio equipment and the physical property more feasible than in earlier years where a full-time human presence was required.
