14m extension (incl. belt and clamps) to your 12m HD Fiberglass pole

Simply upgrade your existing 12m HD mast to a 14m HD mast!

You will receive three new tube segments and two rubber caps and accessories to convert your 12m HD mast in one minute.
Simply remove the old main tube from the 12m HD mast and attach the three new segments "at the bottom" instead (insert the remaining eleven segments of the 12m mast into the new three), fit new rubber caps and you're done!

Bottom diameter: 65,5mm
Top diameter: 8mm (Top diameter of the extension's 3rd segment is approximately 57mm)
Wall thickness: 1.4mm (top) - 2.1mm (bottom)
Number of segments: 14 (Extension includes 3 segments)
Material: Fiberglass, black, UV-resistant, multi-layered specially reinforced winding

The new and taller Spiderbeam Heavy Duty fiberglass pole is perfect for building a wide variety of wire antennas.
A single person can easily erect the pole within a few minutes. Specially reinforced and specially developed as a result of our ongoing efforts to create even more rugged and reliable portable equipment!

Our HD versions are extremely robust poles, with significantly thicker walls (up to 2mm!) than common "fishing rods". They are manufactured using a specially reinforced winding method - several layers of fiberglass wound in alternating directions (lengthwise/crosswise) result in significant reinforcement in the lengthwise and crosswise directions. Stronger joints have also been achieved by significantly increasing the overlap between the individual tube segments.
Whereas other fiberglass fishing rods and poles have a top segment usually as thin as a "horse whip" and therefore hardly usable for anything, the top segment of this new pole is 8mm in diameter (and 1.4mm wall thickness), the same as the 12m HD pole’s top segment. You can use the full 14m length of the pole for a wire antenna or similar. During our tests, we were able to attach an 80m Inverted-V dipole (made of 1mm enameled copper wire) at the very top of the mast, which is not possible with a "fishing rod" under any circumstances.

Spiderbeam Heavy Duty poles are ideal for building 40/80/160m wire verticals or inverted L antennas. (Lee W9OY, for example, used them to build a powerful 80/40m vertical).
They are also good for lightweight 1-element quads or delta loops for 40-10m, or dipoles for all bands, especially when fed with balanced feedline (e.g., Window-Line or true Ladder-Line) instead of heavy baluns. The construction of lightweight beams for 40 and/or 80m is feasible using 2 or more of these poles.
The best wire to use with this pole for most portable operations is our “PolyStealth-22” (insulated, stranded copper-weld wire). It is thin, lightweight, yet very robust.
Spiderbeam’s 1mm Kevlar guy rope (alternative: Spiderbeam’s PVDF Monofil Line) is perfect for guying the wire antennas. For heavier-duty applications, use our “PolyStealth-18” wire and 1.9mm Kevlar guy rope or the 2.5mm Dyneema.

Due to the 14m version’s larger diameter at the bottom, wire antennas such as our Aerial-51 807 or 404 can be installed even higher on this pole than on the 12m pole.

Many customers have expressed the wish for a fiberglass pole with the same collapsed length as our 12m pole but sturdier at the top. At a height of 12 m, this new pole has a diameter of over 17 mm (over 5/8 in.) at the top, giving it unparalleled stability at such heights. Yet it fits into the same travel bag as our 12m pole.


As this mast is basically an extension of the successful 12m pole (and backwards compatible) you can expect the same experiences as we had when we tested the 12m pole in December 2004 on the North Sea in wind speeds of up to 120 km/h!
We have achieved the same stability with the 14m pole in recent tests.

For installations of longer duration, we recommend using the clamps and two guying belts for securing the pole. The guy belts absorb the wind forces perfectly and protect the fiberglass material. When guyed at 2 levels and secured with clamps, this 14m HD pole can be erected outside for months, or even many years without worry.
The material to build the two additional clamps for your old 11 hose clamps is included here. At this height, we strongly recommend using all clamps for locking.
And we recommend two guy belts for guying (your old 12m HD guy belt for the top and the new guy belt supplied with this set for the bottom).

Order now and enjoy portable operations with the largest HD pole of the new generation!

Accessories for permanent installation included in this set:
- Material set to build the additional clamps with rubber padding for the new segments are included in this set. (You should use your old 12m clampset for the rest of the new 14m Pole).
- The additional lower guy belt for the 14m pole is included here (you should use your old guy belt of the 12m HD Pole as the upper guying point on your new 14m pole.)

Also highly recommended: Our new (Heavy-Duty) “GoPak Set 2.0” with the strong part of this pole reduced to 12m.
This means that the 404-UL antenna can be attached directly to the top and, at a height of 12m, is even better than at 10m on the 12m HD poles.


Note: All models of our fiberglass poles can be easily shortened by any number of segments. (Simply open at the bottom and remove unneeded segments). This enables you to use only the desired number of segments required to reach the desired length. For instance, you may remove (top) segments from our 18m pole, converting it into a stiffer 14.9m pole, or convert a 14m pole into a stiffer 12m pole....etc.

Also highly recommended: Our new (Heavy-Duty) “GoPak Set 2.0” with the strong part of this pole reduced to 12m.
This means that the 404-UL antenna can be attached directly to the top and, at a height of 12m, is even better than at 10m on the 12m HD poles.


Also highly recommended: Our new GoPak Set 2.0 with the strong 12m part of this mast. So that the 404-UL antenna can be attached directly to the top and is then even better with a height of 12m than with a height of 10m on the 12m HD mast.
