TheSwingate transmitting stationis a facility for FM-transmission in the village ofSwingate,nearDover,Kent(grid referenceTR334429). For many years there were three lattice towers with a height of 111 metres (364 ft). This station was one of the first 5Chain HomeRadar stations completed in 1936 and was originally designated AMES (Air Ministry Experimental Station) 04 Dover. The FM transmittingantennasare attached to what was the middle tower;microwavelink dishes andmobile telephoneantennas were spread across all three towers. The south tower was dismantled in March 2010, as a result, only two remain.

The Swingate towers no longer have the three cantilever platforms that were fitted originally.

History

Originally there were four towers with wires stretched between them to transmit radio waves that were detected by a group of four smaller towers to the east of the surviving ones. The receiver towers were demolished after the war, along with one of the transmitter towers. Subsequently the north mast was demolished and replaced with a similar tower with a different bracing design. During the Cold War the towers sprouted four transmitters at their base which were popularly assumed to be part of the USACE Highcommunication system but were more likely an RAF link to Germany. The south tower was dismantled in March 2010.

Timeline

In 1936, four transmitters with platforms were erected. In 1955 one transmitter was dismantled, leaving three standing. In 1991 the north tower was replaced by a shorter one. In 2010 the south tower was dismantled.
