Spiderbeam Antenna Accessories
Rugged Portable Telescopic Aluminum Mast Assemblies
We can supply a range of professional quality telescopic masts for radio communications, field lighting and surveillance applications.
These mast’s are constructed from anodized aluminum tubing sections of various lengths and diameters, all with a wall thickness of 2mm. These mast’s are ideal for both temporary and permanent installations. These mast’s are manufactured by Spiderbeam Gmbh.
Transportation or collapsed lengths vary from 1.35M to 2M and some mast’s can be supplied in a standard or heavy duty version.
The heavy duty versions are intended for permanent installations.
A range of accessories including 3 and 4 hole guy ring sets, tripod bases, guying cable, mounting kits, rotator mounts plus many specialized fittings.
The individual tube sections are interlocked with strong high quality stainless steel clamps with hex socket screws. A hex socket wrench is supplied with each mast. No further assembly tools are necessary. A mast should be guyed at two or three levels.
There are five mast lengths 10M (33’), 12.5M (41’), 14.5M (47’), 15M (49’) and 18M (60’)

| 15M | 15M (49’) | 2M (6’7”) | 30mm | 70mm | 9 | 14.0 |
| 14.5M HD | 14.5M (47’) | 2M (6’7”) | 40mm | 80mm | 9 | 18.0 |
| 18M | 18M (60’) | 2M (6’7”) | 30mm | 80mm | 11 | 18.0 |
When properly installed these mast’s are quite capable of supporting most VHF/UHF beams and wire antenna’s. The HD or heavy duty mast’s should be used with heavier HF beam antenna’s similar to the heavy duty Spiderbeam.

Spiderbeam Kit
The Heavy Duty Spiderbeam is a specially reinforced version, optimized for permanent installation at home (see chapter 4 of our construction guide PDF). Doubling the wall thickness of the aluminium and fiberglass parts added a lot of extra ruggedness to the design, making it strong enough to permanently survive severe weather conditions for many years. All parts are made from high quality materials resistant to weather, UV rays and corrosion.
The well proven electrical concept remains unchanged: 3 monobanders are interlaced on one boom, forming a highly efficient 3-band yagi. At 10.7kg this full size beam is still a lightweight, compared to many other permanent yagis in the same performance class. You will find suitable aluminium masts here. Please read above this product.
Putting together this antenna kit will be a fun and educational project. It contains all the necessary parts to make a 100% complete antenna, as described in the construction guide. Nothing beats the satisfaction of cracking pile-ups with an antenna you built with your own hands!
Welcome aboard. Over 700 spiderbeams are already installed worldwide.

HD 12 metres Fibreglass Pole
Spiderbeam Heavy Duty fibreglass poles are perfect for building all kinds of wire antennas.
A single person can easily put them up within a few minutes. Especially developed to make our portable equipment even more rugged and durable!
These are extremely strong poles, with a much greater wall thickness (up to 2mm!) than the usual “fishing rod” types. A special reinforcing winding technique – several layers of fibreglass are wound in alternating direction (criss/cross winding) – provides greatly increased lateral and linear strength. Stronger joints are achieved by a much larger overlap between the individual tube segments than usual.
High strength professional telescopic fibreglass pole
| Fully extracted length (height) | 12m (40ft) |
| Transportation length | 1.18m (3ft 10″) |
| Weight | 3.3kg (7lbs) |
| Bottom diameter | 55mm (2 1/6″) |
| Top diameter | 8mm (1/3″) |
| Wall thickness | 1.4mm – 2mm (1/18″ – 1/12″) |
| Number of segments | 12 |
| Pole material | Black fibreglass, UV protected specially reinforced multilayer winding |
Clamps
Complete set: – Contains 11 stainless steel clamps with rubber padding.
(For portable installations, most people simply use sticky tape for locking the individual tube segments, and this works very well!)
However, clamps are the perfect method to securely lock the segments of the fibreglass mast for a long period. They are especially suitable for permanent installations and superior to all other locking mechanisms (tape, glue, cable ties).
They have a very strong grip, yet they can be removed easily even after years of installation.
Install the clamps as follows:
Simply put one clamp at the very bottom end of each tube segment and tighten the clamp. Here it will act as a stopper and prevent the tube from sliding downwards into the next bigger tube segment.
The rubber padding is made of a thick flat rubber band, protecting the mast against any damage from the clamps.
Guy Belt for 12m Fibreglass Pole
This strong guy belt is an ideal method for quickly attaching guy ropes to the pole. The belt is very flexible and lightweight and transfers the forces into the mast over a very large area, thus preventing damage.
Simply slide the belt over the mast.
The belt rests at the bottom of the 8th segment with a diameter of 27mm (= approx. 7m height).
Attach 3 or 4 guy ropes (in 90° or 120° directions) and tie them to ground pegs at a distance of approx 5m from the pole.
Spiderbeam 18m (60ft) Fibreglass Pole
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 easily “walk up” the pole within a few minutes.
Spiderbeam 18m (60ft) fibreglass poles are built very similar to our well proven 12m HD fibreglass 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 dia /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 fibreglass 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 dia) enamelled copper wire or similar.
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 dia) or 2mm Kevlar rope very suitable for guy lines.
High strength professional telescopic fibreglass pole
| Fully extracted length (height) | 18m (60ft) |
| Transportation length | 1.70m (5ft 7″) |
| Weight | 6.8kg (15lbs) |
| Bottom diameter | 73mm (2 5/6″) |
| Top diameter | 4mm (1/6″) |
| Wall thickness | 1mm – 2mm (1/25″ – 1/12″) |
| Number of segments | 12 |
| Pole material | black fibreglass, UV protected specially reinforced multilayer winding |
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.
Each pole includes a Free Stainless Steel Clamp Set!
Guy Belt for 18m Fibreglass Pole
These strong guy belts are an ideal method for quickly attaching guy ropes to the pole.
The belts are very flexible and lightweight and transfer the forces into the mast over a very large area, thus preventing damage of the fibreglass tubes.
Set contains two belts for guying our 18m fibreglass at two levels. Simply slide them over the mast.
The 52mm belt rests at the bottom of the 5th segment (= approx. 7m height).
The 32mm belt rests at the bottom of the 9th segment (= approx 13m height). Attach 3 or 4 guy ropes (in 90° or 120° directions) to each belt and tie them to ground pegs at a distance of approx 8m from the pole.
2 mm diameter high strength Kevlar guy line.
Use it for guying 12 m and 18 m Spiderbeam Fiberglass Pole
- Breaking strength: 150kg
- Weight: 4g per meter
- Very low stretch: 1%
- UV resistant
- 2 mm diameter high strength
