I am now the proud owner of a 8m collapsable carbon fiber roach fishing
pole.

I live on the 9th floor the (top floor) of an appartment block. I have
a hemi-eliptical balcony, about 3-4 meters across, I have a steel
balcony railing streching around enclosing it. There is a steel drain
dipe running through one corner of the balcony. I have unlimited
height (blue sky). I thought of lashing (or using sterling hose
clips) to secure the first section of the roach pole to the one corner
of the balcony, then I thought of using the top of the fishing rod to
suspend one end of a trapped dipole or G5RV(?) antenna, and fixing the
other via an insulator to an eye hook in the wall...

Only problem is the pole might be struggling to support the weight of
the trapped dipole.....(?)

With the above features, what would be the optimum 10, 20 and 40m
solution given the space I have, roach pole (supports limited weight),
drain pipe (good ground??), balcony etc...

Either commercial or homebrew, prefer home brew....
