Sectional Monopole Tower Foundation & Installation Manual, Revision A

Installation Personnel

Southwest Windpower strongly recommends professional construction of the foundation. Constructing the foundation requires specialized equipment, 
experience constructing concrete forms and knowledge of local zoning and building codes and inspection requirements.

Skystream Dealer

Skystream Owners who are considering constructing “any or all” of their foundation, or raising their own tower 
should completely review this manual and the Skystream Owners manual before proceeding. Working with high 
voltage electricity, constructing foundations and raising and lowering towers can be dangerous. And mistakes can 
be expensive. 

Understand what you are getting into before starting

.

Owners should also be aware that many localities require installation by “certified installers” or by licensed contrac-
tors to qualify for clean energy monetary rebates. 

If you decide not to install the tower yourself, dealers displaying the “Skystream Dealer” insignia shown here, have 
completed factory training on the correct and safe installation of the tower (and Skystream).

IMPORTANT: 

Do not pour concrete before 

all required permits are obtained, inspec-
tions completed, and you are authorized 
to proceed.

building Permits and Zoning Requirements

Building codes and installation requirements may vary greatly depending on state, city, and local town-
ships. Be sure to obtain all required building permits BEFORE beginning the installation.

Be sure you understand all installation and inspection requirements. Many localities require inspections 
at key phases of the installation before additional work can proceed.
