Whisper 500 Windistar 4500 60' Guyed Tower Kit
Uses 5" schedule-40 pipe.
This tower kit is designed specifically for the Southwest Windpower Whisper 500 and the Windistar 4500 wind turbines. 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. Read the system planning section of the Owners Manual and determine the 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.
