I had the 18m spiderpole and now I am using the 22m spiderpole.
It is guyed with 4x2 guys.
It is a stable mast. I raise it by hand by extending the tubes one by one.
I would not place the mast over another tube. The tubes cannot handle
force from inside.

I used to do exactly what you asked. I joined a 6m aluminium scaffold pole
to an 18m Spiderpole using one of the couplers sold by Barenco

I raised it exactly as you suggest, with a falling derrick. It took less

Thanks, I had the same idea but I am concerned about the point pressure at the
end of the scaffold pole on the inside of the Spiderpole, since on raising and
lowering that would be at its extreme.I came to the conclusion of using a
"soft" buffer to spread the contact pressure. I
Well some telescopic fibreglass masts will fit over an alloy Scaffold Pole,
so you just slide it over and fit a Jubilee Clip a couple of feet down.
Otherwise, it's down to buying some tubing to act as a joining sleeve . . .
where the inside diameters are different I have known people use a
Further to that scheme, is there a sound way to join a Spider pole to a
scaffold pole? The cost change from 18m Spider to the next sizes up is quite a
jump, but I've often thought an alloy scaffold pole at the base would be worth
the effort if I had a decent way to join them. I can raise the
David I'm inclined to agree with the other Gs . . . you could do this MUCH
more cheaply yourself (maybe a tenth of the cost) . . . and probably make a
stronger and more efficient antenna.
21ft thick-walled alloy scaffold aren't that expensive, yet are extremely
strong . . . and if you see a

I'm sure you must have some tall trees down there in the Dart Valley! You
could save yourself a bundle in shipping charges alone by putting up a
simple wire inverted 'L' or a 'T'.
Use a pneumatic tennis ball launcher to place the halyard over the tree at
the highest point. I have
