Spiderbeam 18m (60ft) fibreglass poles are designed with durability and balance in mind, following the success of the 12m HD fibreglass poles. The poles feature a sturdy build with varying diameters and wall thicknesses along their height, starting at 73mm diameter and 2mm wall thickness at the base and tapering down to 40mm diameter and 1.5mm wall thickness at 10m height.

The special reinforcing winding technique of these poles' construction is a vital feature. Multiple layers of fibreglass are wound in alternating directions, providing increased lateral and linear strength. This design ensures the poles are suitable for various wire antennas, such as 80/160m wire GP or inverted L antennas, lightweight 1 Element Quad or Delta loops for 40-10m, and dipoles for all bands when paired with an open wire feedline.

In terms of specifications, the Spiderbeam 18m fibreglass pole is a high-strength telescopic pole with a fully extended height of 18m (60ft) and a transportation length of 1.70m (5ft 7"). Weighing 6.8kg (15lbs), the pole features a bottom diameter of 73mm (2 5/6"), a top diameter of 4mm (1/6"), and a wall thickness ranging from 1mm to 2mm (1/25" - 1/12"). With 12 segments of black UV-protected fibreglass and specially reinforced multilayer winding, these poles offer reliability and performance for antenna installations.
