Thanks, John. The mast will be directly under the Tx antenna, the receive antenna is a horn or LPDA 3m away. I need the antenna to be "completely" (not visibly swaying) when stationary. I'm trying to use as small a diameter tube combination as possible, to minimize the surface area that can reflect. That's true of any material, FWIW. I thought that one of the telescopic solutions had locking couplers at the jointswhich would achieve the level of stiffness I need. If not, i could fabricate couplers that positively locked sections in place. The 21" requirement is so it can fit in a standard carry-on bag. do you think I can achieve enough stiffness using carbon fiber, either using the locking mechanisms available or by fabricating my own?

I'm building a mast to deploy a measurement antenna, a small omnidirectional biconical, with a 1-18GHz range. Carbon fiber seems to be an ideal material which will cause minimal interference or reflections. I need the mast (pole) to collapse to < 54 cm (21"), and extend to > 2.5m (100"). It will be supporting a weight centered on pole, and weighing <5 lbs. Which is the best telescopic solution that Rock West offers? Do I need a custom piece, or can I modify an available design? Thanks in advance for any assistance, please let me know if I can answer any questions.
