The Snaefell ATC mast in 2018.  Still providing links between aircraft and the current ATC centres at Prestwick and Swanwick.  The mast has no doubt been replaced or upgraded and the transmitter/reciever builing has been enlarged considerably.  Apparently the original building is still contained within the new shell though.
