The '''Swingate transmitting station''' is a facility for FM-transmission at [[Swingate]], [[United Kingdom|UK]] (national grid reference: TR334429 ). For many years there were three lattice towers with a height of 111 metres, which were built for [[Chain Home]] [[radar]] before [[World War II]]. The FM transmitting [[antennas]] are attached to what was the middle tower; [[microwave]] link dishes and [[mobile telephone]] antennas were spread across all three towers. The south tower was dismantled in March 2010.

They are the only radar towers from the [[Battle of Britain]] in WWII still in use today, although 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 US [[ACE High]] communication 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.<ref>{{cite web |author=Lorraine |title=Part 3 Swingate, Radar and the Towers |url=https://doverhistorian.com/2015/02/07/part-3-swingate-radar-and-the-towers/ |website=doverhistorian.com |publisher=The Dover Historian |access-date=14 March 2021 |date=7 February 2015}}</ref>

=== High Frequency Trading ===

Several of the microwave dishes located on one of the towers provide connections via a chain of towers between the NYSE Euronext datacentres in Basildon and Slough, and Frankfurt for use in High Frequency Trading

The transmitter is the main transmission station for the [[BBC]] which serves the bulk of Kent.<ref>Radio Listeners Guide 2010</ref>

'''Digital Radio'''

There are currently no [[Digital Audio Broadcasting|DAB]] signals from this site at present due to its proximity to mainland Europe. The county of Kent is therefore covered with smaller, low-powered relay stations instead to avoid interference.
