Glass fibre mast, single tubes etc.

Heavy Duty Fibre glas mast

HD-Fiberglasmast 10m

10m 'Heavy Duty' fibre glass mast, reinforced version. Sizes comparable to the standard 10m mast, but much more solid.

The diameter of the topmost tube is approx. 11mm, the lower most tube has a diameter of 45.8 mm at the lower end. The wall thickness is approx. 1 mm at the top and approx. 2 mm at the lower tubes. This makes this fibre glas mast nearly rigid, the mas tcan carry lightweight small yagi antennas, LogPer antennas or light wires. But also cameras, small anemometers or small lights can be mouted at the top. The HD fibre glas mast consists of ten segments, the extended length is slightly more than 10m, transport length is 117cm. Weight 1.7kg.

The lower most tube is closed with a rubber plug which aligns with the diameter of the lower tube. I.e. the plug does not contribute to the diameter. This plug is glued into the lower most tube and can not be removed. The result is that segments which are not required can not be removed. Just leave not required segments inside the lower most tube.

Diameters of all tubes at the topmost end (all values approximative): 11, 14.5, 17.1, 20.7, 24.3, 27.5, 31.1, 34.6, 38.6, 43.2 mm.

Mast Extension für HD Mast New!

The HD FIbre glas mast 18333.10 can be extended with up to 5 extension tubes, making the mast longer by approx. 4.5m. One extension (ref. 18334) consists of a 112cm long, conical tube made from very solid fibre glass material. An additional adaptor ztube (ref. 18334.01) connects the HD mast and the first extension tube. Each further extension does not require the adaptor, it fits into the previous extension.

The first extension tube extends the 10 m HD mast by about 66cm, due to the long overlap. Each further extension adds another 97cm. With maximal five extensions the 10m HD mast can be extended by 4.5m in total. The extension tube as ha diameter of 50 mm at the top, and about 56 mm at the bottom. Weight of theextension 560g, weight of the adaptor tube 310g.

The extension tubes can be used alone for a solid mast with nearly constant diameter. The number of tubes is only limited by the top load and by the guying of the mast. One of the 40cm long adaptor tubes could be used at the very top to protect the end of the mast and provide better fastening for $ntennas etc.

Carrying Bag for masts and antennas

18335: Carrying Bag
18335: Carrying Bag

Versatile carrying bag for portable masts and antennas.

The carrying bag 18335 is very well suited to transport and store multiple portable masts, collapsed antennas for VHF or shortwave, cables and other accessories. The bag has two separately accessible compartments and a length of 116cm.

The carrying bag has long carrying handles, with these handles the bag can be carried like a back pack, for example on mountain tours where you need your hands free. The handles of the zipper fasteners are long enough to be used even with gloves.

The materials are made of strong synthetic fabric with edge protection. Total weight (empty) 900g. Colour black.

Spiderbeam 18m Fiberglass-Mast

Especially developed for portable use on the low bands 80 and 160m. Ideal for constructing various wire antennas, for example 80/160m wire verticals, inverted Vee or inverted L antennas. Many DX-peditions use these masts to build a 4 square antenna for 80 or 40m. A portable 80m 4-square can be set up in about one hour. Equally suited for light 1 elem. quads or Delta Loops for 40 to 10m.

A single person can set up one mast in a few minutes.

Low weight, very solid lower sections (73 mm diameter, 2 mm wall thickness), in 10m height still 50 mm diameter at 1.5 mm wall thickness. Light segments on top (1 mm wall thickness) for good balance. The reinforced laminating technique - many layers of fibre glass in different directions - results in significantly stronger segments. All masts are supplied with a free stainless steel clamp set.

Spiderbeam 26m Fibre glass tower


26m Mast

Gigantic fibre glass tower with 26m height!
Solid construction with low weight and only 2m transport length. The fibre glass tubes are black and UV resistant, wound with multiple layers and reinforment rings. The wall thickness is 2.mm on the lower end, and 1 mm on the upper end.

Such a master open a whole new world of possibilities. How about a 160m vertical with top load? Or a fullsize vertical for 80m, or even a portable 4-Square for 80m? Or build a 1 element Quad loop for 40m!

The installation can be done by two persons in about one hour, with a little practice also faster. Included in the shipment are 14 rubber-padded clamps and three guying rings. Additionally you will need gyuing lines, e.g. our light 3 mm Dyneema rope (Ref. 23100), plus material to fix the rope to the ground (ground pegs etc.).

Sturdy Glass Fiber Mast



Compared to the light weight 'fishing rods' this mast is suitable for the installation of short wave or V/UHF beams up to 12 Kg weight or heavy wire antennas (e.g. inverted vees, delta loops etc.). The mast works for stationary applications like replacement of wooden towers and for insulated installation of wire antennas; the mast is also suited for portable use durind DXpeditions or just for the weekend QTH.

The masts are made of ultra violet resistant fiber glass telescopic pipes of 1.5m length and 60 mm diameter; they are much more rigid than compared to the well know aluminum masts. The masts are available in various lengths up to 12m togther with the required fittings.



The basic model MV-75 has a length of 7.5m and can be set-up by a single person within 10 minutes. The mast is rotatable while guyed and has a total weight of 12 Kg incl. the mechanical fittings K-75; the maximum allowable wind speed is rated at 130km/h.

The armature kit K-75 contains the base plate kit with 4 ground pegs for fixation, a guy rope (must be cut to length by the user) with guying fixation and 4 ground pegs, and the top assembly with mounting material. The vertical tube of the top kit has a diameter of 40cm and a useable length of 19cm. The horizontal tube on the top assembly has a diamter of 16 mm and a length of 8cm on each side. The ends of the horizontal tube have holes for installation of a pulley of shackle.

With the extension kit K-12 the mast can be extended up to 12m. An appropriate guying rope is available for the extension to 12m.
