Why not? I think there some pictures in ON4UNs book showing someone
walking out on the boom of a very large antenna.
I would imagine, too, that they used a suitable crane to get the parts up.
56m is substantially lower than the height of readily available
construction cranes.
There are riggers who work with this sort of thing everyday. Think about
big construction cranes on tall buildings, or bridges. There are even
people who do it on LIVE 700 kV power transmission lines.
it IS an impressive beast. weighs a bit (3.3 US tons), too.
