Constructed out of angle iron. The base holding the rotor is set off the concrete pad by 4 inches allowing easy access to the bolts securing the rotor. A solid steal rod is welded to the bracket that holds the base of the tower and is supported by a TB3 thrust bearing. (directly above rotor) The bottom plate holding the rotor is secured by anchor bolts in the concrete pad the base sits on. A quick connect is used to quickly disconnect the rotor for removal.

This is the bracket that holds the tower to the back plate while allowing the tower to freely rotate.

2 pieces of angle iron bolted to the sides of the 4X4 support. Solid nylon was milled out to the with of the super heavy strap attached to the winch. The end of the strap is fitted with a heavy duty coupler that attaches to the the upper part of the tower when raising or lowering is required.

You can see the strap attached to the cable on the tower (running parallel to the ground toward the bottom of the tower). The strap is removed from the cable after tower is raised and the cable is secured to the tower with a bungy cord so it does not clank in the wind.

The hole for the 4X4 which supports the tower is 4X4X4 filled with concrete and acts as the pad for the tower base.

Tower is 40', base is 2' and mast is 10' for a total height of 52'.

four elemens on an 8' boom. Cheap and durable. See link for detailed construction article.

My friend Bill W2DGB wanted to get on 6 but with something a little smaller so I modified the 4 element design to 3 elements.
