This is how my tower with cantilevered section looked recently when
working over part of a neighbour's house.

Yours appears to be putting torsional loading on the tower.. something they
are not designed for.
Their examples transfer the load to the structure beneath which is how
towers are designed to be used.
Just remember that when you start to load it.. epecially with an alloy tower
as there is little(no!) warning before it goes.
