Southwest
Windpower
This tower kit is designed specifically for the Southwest Windpower Whisper
500 wind turbine. To our knowledge this is the most economical and user-friendly
tower kit available for the Whisper 500 wind turbine. The tower kits are
designed to use guy wires, allowing the use of schedule 40 pipe while
providing adequate strength, even in high wind conditions. At least two
people should be present to safely raise the tower.
While simple in concept these towers require basic mechanical aptitude and attention to detail. See the manual and analysis documents in the Product Documentation section above to determine the best location for the tower. It is much easier to work with nearly level ground. Parts listed to construct these towers are readily available in most parts of the world.

Although I really wanted a monopole tower for my Skystream 3.7, shipping for one of those was outrageous. Southwest Windpower does not allow pickup at their location either. So, I chose this tower kit, found some 5 inch pipe as specified, dug 5 holes
