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
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.
