Very well suited mast for Fieldday and DXpeditions - small and lightweight!
This mast fits together nicely with all our portable Spiderbeam yagis. (For a picture with 2 Spiderbeams installed on such masts see the Installation hints). It will also carry a Heavy Duty Spiderbeam at a reduced height of 9m (29ft).
The individual sections are interlocked with strong high quality stainless steel clamps with allen screws. An allen wrench is supplied with the mast and no further tools are necessary. The mast should be guyed at one or two levels.
This mast was developed for all types of portable operations & DXpeditions. With a transportation length of 165cm it is easy to transport by car and can be carried on most airplanes. At its full height of 12.5m it will easily carry a portable Spiderbeam yagi. The mast can be rotated by hand, or a rotator (e.g. KR-450 or KR-650) can be placed at the bottom and turn the whole mast including the Spiderbeam.
note: The tubes of our aluminium masts are anodized for surface protection. Due to increased contact resistances between the individual tube segments the mast cannot be used as a radiator for vertical antennas without further treatment.
