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 of high quality materials resistant to weather, UV rays and corrosion.
The well proven electrical concept remains unchanged: 5 monobanders are interlaced on one boom, forming a highly efficient
5-band yagi. At 11.5kg this full size beam is still a lightweight, compared to many other permanent yagis in the same
performance class.
ATTENTION: this is the partially prefabricated antenna. The wire set was measured, cut and pre-assembled by hand to be able to attach it to the spreaders. You will receive all components and the complete wire set ready wound on a plastic spool. This saves you the hours of preparation and you can devote yourself entirely to the construction of the antenna on site.
Info: This pre-assembly means a few hours of pure manual work.
The pre-assembled wire set can therefore take 1 week or longer, depending on demand and capacity utilization in production.
