Extended 18m high mast for Fieldday and DXpeditions!
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 14m (46ft).
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 three levels.
This mast was developed for serious portable operations & DXpeditions. It is still easy to transport by car and can be taken aboard normal sized airplanes. It will also serve well for building permanent 80m vertical antennas etc.
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.
