Wimo Heavy Duty Telescoping Fiberglass Mast Extension Kits add to the bottom of and extend the height of the WMO-18333-10 Heavy Duty Mast. With appropriate guying, use one WMO-18334-01 Adaptor Tube and up to five fiberglass WMO-18334 Extension Tubes can provide a total of 14.76 ft. additional height. The first extension tube extends the Heavy Duty mast by approximately 2 ft. due to the required tubing overlap and each additional extension tube adds another 3 ft.

*IMPORTANT *
One WMO-18334-01 Adapter Tube (sold separately) is REQUIRED to connect the first WMO-18334 Extension Tube to the bottom of the Heavy Duty Mast. Each additional Extension Tube does not require this adaptor; as they are tapered to fit onto each other.

WMO-18334 Extension Tubes can also be used to create a very portable and easy-to-assemble stand-alone mast that maintains a larger diameter for greater strength. The number of Extension Tubes used for this alternative mast is limited by the top load and guying of the mast. One of the WMO-18334-1 Adapter Tubes could be used at the very top of that alternative assembly, to protect the mast top and provide a robust antenna fastening point.

Specifications of the WMO-18334:
* Extension Tube Length – 3.67 ft. (112cm)
* Extension Tube Top Diameter – 1.969 in. (50mm)
* Extension Tube Bottom Diameter – 2.165 in. (56mm)
