I bought a spiderbeam antenna for permanent use in singapore.  i should have bought a telescoping mast to go with it, because it's otherwise impossible/impractical for me to elevate.

I'd like the mast to allow a rotor, as well.

Spiderbeam sells nice telescoping masts that would allow a rotor on the bottom, however they are damn expensive (300euro for an 11m pole) [plus all the shipping from europe]

anyone know of any feasible alternatives that are less expensive?

Rohn makes a 44-foot telescopic mast that I have used for my 20m Moxon (with light-duty rotator).  I removed the top-most section as it is pretty small-diameter stuff, but the mast is usable in the 35-foot range if properly guyed.  The cost for the Rohn mast was around $80 USD.  I don't know if you can get one there, but they're fairly decent in my opinion.  In the US, Channelmaster makes a similar mast, but it is smaller in diameter than the Rohn mast.

Hope this helps...

...Rohn also make a nice 50 footer too . Again, with the top section removed, it handles my hex beam, and Channel master at 40 feet.

I once used an aluminum extension to ercet a j-pole 45' in the air. It worked great. I secured it against my deck with ropes as a temporatry antenna. I used it for a bit longer than I intended to since I didn't use the ladder for much of anything else. Emphasis on temporary.
