18m "KingSize"
Spiderbeam 18m (60ft) fibreglass poles are built very similar to our well proven 12m HD fiberglass poles, yet carefully designed to maintain low weight and perfect balance.
The pole starts out very rugged at the bottom (73mm diameter / 2mm wall thickness) and still has 40mm diameter / 1.5mm wall thickness at 10m height
A special reinforcing winding technique - several layers of fibreglass are wound in alternating direction (criss/cross winding) - provides greatly increased lateral and linear strength
The poles are perfect for building all kinds of wire antennas, especially 80/160m wire GP or inverted L antennas. They can also easily support temporary lightweight 1 Element Quad or Delta loops for 40-10m, and dipoles for all bands, especially when used with open wire feedline.

Pole installation
- One person can easily "walk up" the pole by pressing the bottom against a rock, tree, car or ground anchor, or having a second person hold it.
- Once the pole is in vertical position, it can easily be moved around.
- Fix the bottom to a ground anchor and attach guy lines at 2 levels. Thin fishing monofilament (1mm diameter) or 2mm Kevlar rope is very suitable for guy lines.
- To complete the installation we strongly recommend using our rubber padded stainless steel clamps to safely secure the telescoping elements from slipping down.
- For a pole of this large size, clamps are a better solution than using tape only.
