Robust 18m telescopic Spiderbeam mast for HF VHF UHF and wire antennas

No review at the moment

The Spiderbeam Heavy Duty 18m fibreglass mast is a good choice for using a wide variety of 40/80/160m long-wire and GP or inverted L antennas, lightweight 1-element Quad or Delta loops for 20-10m, as well as dipoles for all HF and VHF-UHF bands, this mast can support small VHF/UHF yagi antennas to a height of 9-10m.

This 18m telescopic mast can be erected in a few minutes by a single person and has been specially designed for the robustness and durability requirements of portable equipment. It measures 118cm when fully folded.

It has a much thicker wall, 2mm at its thickest, than the usual "fishing rod".

It can be used with AWG 18 (= 1mm diameter) enamelled copper wire or similar to build vertical antennas, loops, dipoles, etc.

For guy wires, fine fishing monofilament (1mm diameter) or similar rope is ideal.

Supplied with: 1 Spiderbeam 18m mast and 11 rubber guy ropes.

Specially reinforced multi-layer winding

* Due to production variations, the dimensions shown may vary slightly. This does not affect quality or performance.

Unlike the poles offered by most competitors, the top segment of the Spiderbeam mast is not a very thin, fragile whip. Instead, this mast can be used to its full 18m length, offering great flexibility and optimum use of height.

It uses a special reinforcement winding technique, where several layers of glass fibre are wound in an alternating direction (cross-winding), which considerably increases their lateral and linear strength.

The joints between the different tube segments are also strengthened thanks to a larger-than-usual overlap.

Unlike other poles where the top segment is very thin like a whip, the top segment of Spiderbeam Heavy Duty poles has a diameter of 40mm (and a wall thickness of 2mm), allowing them to be used over their full 18m length.
