The Decca Legacy - Chapter 15 - Wootton Bridge

An early move from transformer oil was the use of Sulphur -Hexafluoride (SF6) gas as the EHT insulating medium, and this was used in the AWS-5 radar of the 1980''s. This radar used a grid-switched Coupled Cavity TWT having a swept frequency RF drive, but much of the rest of the radar transmitter design remained conventional.
