FOX 26 - This video was found on YouTube. The urban Endeavours posted states this about the climb.a
"After 3 months of steady research and training, we determined this tower was deactivated and safe to climb, and that I was fit to climb it. The ascent took 2.5 hours and the descent 1.5 hours. This was the most unreal thing I've ever done. From my findings, this is currently the World's Tallest Freeclimb of an Antenna at 475m."
