Back in the mid '90s, I had occasion to climb a 145m (475ft) self supporting tower in connection with my position as Transmitter Tech.
The bottom part of this type of tower is not too bad, pretty,much like a building without cladding.
The ladder shakes a bit on the first bit along the leg, but after the first level, it feels more secure.
Those first couple of levels are quite nice, you can stroll around, or sit down for a rest.
As the climb moves into near vertical it gets harder
You are a bit pooped by the time you reach the last (very small) level, where you go to another ladder which
goes up behind the antenna panels, but it is then only a short climb to the very top, where you stand on part of the tower frame to replace the top clearance lamp.
There is no chance of falling inside the ladder cage of the one I climbed, as there is an anti-fall device, in the form of a track up the centre of the rungs, which mates with a trolley attached to your climbing belt.
The top bit, behind the antenna panels, has no cage or safety device, so you are back to climbing free, hooking on, when you need to.
And it is bloody cold up there!
That wicked Westerly wind, known as the "Fremantle Doctor" is at full strength up there on the Scarp, once you get above the cover of the trees.
It is what we call a "lazy wind"-----It doesn't bother going round you, it goes through you!
This means that your tongue starts hanging out for a hot cup of coffee, so naturally you start to climb down fast as you can.
The safety device doesn't like this, however, so it lets you get moving, then "stops you falling", giving you an almighty wrench to the back!
I must admit that I felt a bit proud of myself the first time I climbed the tower, until I looked across at the Ch2 tower, where there was some work being carried on.
There they were, Riggers all over the outside of the thing, like aphids on a rose bush!
It put my climb back into perspective.
