Question. Do you guys *not* have surplus military equipment around? Surely!!
A hydrolic or pneumatic mast, or even a handrolic mast makes a good
support for wires and the like.
In the UK we have plenty of ex MOD surplus gear for sale in various
guises. Pump up masts used to mount lights, television stations/film
sets use them, and so do the military for Ahem, mounting antenna's.
Do a web search, you might be surprised what turns up.Dave
