Description
12mHD-E: This is an upgraded version with custom-made stainless-steel eyelet cotter, glued to the top segment with weather-proof and UV-resistant adhesive. The eyelet enables easy attachment of any kind of device to the tip of the pole. 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. 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 (crisscross winding) – provides greatly increased lateral and linear strength. Stronger joints are achieved by a much larger overlap between the individual tube segments than usual.
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. During our tests we were able to put 80m inv vee dipoles (made from 1mm diameter enameled copper wire (AWG 18) and open wire feedline) right at the top of the 12m pole.. No way you can do this with a regular “fishing rod”! At 9-10m height, the poles can easily support small VHF / UHF yagis. A single person can easily put them up within a few minutes. Especially developed to make our portable equipment even more rugged and durable!
