12HD High strength professional telescopic fiberglass pole

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, much better 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.

Spiderbeam 12m Heavy Duty poles are very well suited for building 40/80/160m wire GP or inverted L antennas. 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.

Unlike other poles where the top segment is very thin as a whip. During our tests we were able to put 80m inv vee dipoles (made from 1mm diameter enameled copper wire and open wire feedline) right at the top of the 12m pole. The poles can easily support small VHF / UHF yagis.

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.
