Mast Extension for HD Mast
The HD glass fibre mast can be extended with up to 5 extension tubes, making the mast longer by approx. 4.5m. One extension consists of a 112cm long, conical tube made from very solid fibre glass material. An additional adaptor tube is mandantory to connect the first extension tube to the mast, this adaptor must be ordered separately. 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 antennas etc
