Recently found this rare but excellent video from around August 31, 2011, when TV stations in "mandatory markets" across Canada were shutting down their analog signals... Glen Warren and other tech types here might be interested in this clip. This is some great chopper footage in Barrie, after CKVR's analog channel 3 signal went dark and the old RCA "batwing" transmitting antenna had already been removed from the tower. Mostly shows the riggers going up prior to the digital antenna being installed, but there are shots of the FM master antenna (93.1, 95.7, 101.1 & 107.5) that was installed in the mid-2000s, and the UHF antenna for Radio-Canada's now-dark channel 55 rebroadcaster. https://vimeo.com/123750898
