I couldn't help but notice a similarity between the picture at https://www.bbc.co.uk/news/uk-england-wiltshire-53132567 with the photograph at https://qrznow.com/wp-content/uploads/2015/01/Abh%C3%B6ranlage_Gablingen.jpg This seems to suggest that radio communication is not as recent as you might think? ?
There used to be a Wullenweber DF Antenna at RAF Chicksands in Bedfordshire some years ago when the USAF had tenure. I remember seeing it back in the late 1960's from a coach on our way to the Shuttleworth Trust. Similarly from a ship passing Galeta Island, Panama. Both these now long gone, but the locations still visible in Google Earth. Other than the WW2 German work, most seem to have US origins and I was pleased to see that Plessey in the UK had an involvement too.
