18m Fiberglass pole (incl. clamp kit)

Especially developed for successful portable low-band activities on 80 and 160m!

Imagine building a quick portable 80m 4-square array that you can put up within less than one hour...
A single person can comfortably erect the mast within a few minutes.

Spiderbeam 18m (60ft) fiberglass 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! The upper sections are slim and light (1mm wall thickness), preventing the pole from becoming top-heavy and keeping it perfectly balanced. A special reinforcing winding technique - several layers of fiberglass are wound in alternating direction (criss/cross winding) - provides greatly increased lateral and linear strength.

These 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. (Most baluns would be somewhat heavy). 4-6 poles could be used to build lightweight beams for 40 or 80m (...who is going to build one for 160? :-)).
The best (and cheapest) wire to use for building such wire antennas (verticals, loops, dipoles etc.) is AWG 18 (= 1mm diameter) enameled copper wire or similar.
For feeding wire verticals to our fibreglass poles we offer our Vertical Junction Box / Radial Plate.
The mast comes complete with 11 rubber-padded guy clamps. For guying, our 2mm Kevlar cord is best used in conjunction with the optional tensioning straps.

By the way, all our fibreglass poles can easily be shortened by any segments. (simply open the bottom and remove).
This way you can also use only the desired lengths, such as turning an 18m mast into a stiffer 14.9m mast or a 12m mast into a stiffer 9.90m mast.

Recommended accessories:

- Our strong guy belts.

- Two 50m rolls of 1,9mm Kevlar-ropel or 2,5mm Dyneema
