A single person can easily put them up within a few minutes. Especially developed to make our portable equipment even more rugged and durable! These are extremely strong poles, with a much greater wall thickness (up to 2mm!) than the usual "fishing rod" types. A special reinforcing winding technique - several layers of fiberglass are wound in alternating direction (criss/cross winding) - provides greatly increased lateral and linear strength. Stronger joints are achieved by a much larger overlap between the individual tube segments than usual.They can also easily support temporary lightweight 1 Element Quad or Delta loops for 20-10m, and dipoles for all bands, especially when used with open wire feedline. (Most baluns would be somewhat heavy). 4-6 poles could be used to build lightweight beams for 40 or 80m.Even the top segment is 8mm in diameter (and 1.4mm wall thickness), so the poles can be used to their full 12m length - unlike other poles where the top segment is very thin as a whip. The best (and cheapest) wire to use for building such wire antennas (verticals, loops, dipoles etc.) is AWG 18 (= 1mm diameter) enameled copper wire or similar. Thin fishing monofilament (1mm diameter) or similar rope is very suitable for guy lines.
