Wimo Heavy Duty Telescoping Fiberglass Mast Extension Kits
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)

DX Engineering Aluminum Tubing
DX Engineering High-Strength Aluminum Tubes are ideal for your antenna building projects. It is made available in sizes that fit into and over the next, with close tolerances specifically designed for strength when joined and overlapping only by a few to several inches, to build Yagi, Moxon or vertical antenna elements. NOTE: This tubing is NOT intended for each size to telescope completely into the full length of the next; it cannot be used for telescopic mast building. DX Engineering aluminum tubing is manufactured to very close tolerances. This provides the greatest amount of surface contact between nesting tubes for mechanical and electrical stability. Due to the close tolerance, any burrs, dirt, grit or other foreign material, as well as dents, dings and unseen bending or crushing suffered during shipment will cause binding that prevents this aluminum tubing from fully nesting. 6063-T832 seamless drawn aluminum tubing is available in 3, 6 and 12 ft. lengths. 6063-T832 tubing provides good resistance to general corrosion, including stress corrosion cracking, and an excellent surface appearance. Use a series of 3 ft. lengths to build an element that tapers more quickly for lower wind-resistance applications. Use a series of 6 ft. lengths to make an element that tapers more slowly for greater strength and bandwidth. The 12 ft. lengths are great for HF Yagi construction. Most sizes (except 12 ft.) are available slit on one end for use with DX Engineering stainless steel element clamps. If un-slit ends are required for your applications, merely insert the slit end into the next larger size in the stack and use your own attachment method. 6063-T832 tubing features a 0.058 in. wall thickness and is available in 1/8 in. increments from 3/8 in. to 2-1/8 in. O.D. 3003-H14 drawn aluminum tubing features a 0.035 inch wall thickness and a 1/4 inch outside diameter. Each piece is supplied with non slit ends and is available in both 3 foot and 6 foot lengths, making them ideal for your antenna building projects. If your setup requires maximum strength at very long assembly lengths, then choose DX Engineering 6061-T8 tubing. This heavy-duty version features a 0.120 in. wall thickness and is available in 1/4 in. increments from 1-1/2 in. to 3 in. O.D. Packaged shipments of 6 ft. tubing have oversize shipping fees, regardless of the number of 6 ft. pieces. Therefore, order more 6 ft. pieces to spread oversize fees over more tubing for a more cost effective shipment. Tubing that is 12 ft. long MUST be shipped by truck freight. If you need many pieces of the same size in a 12 ft. tube length, then buying DX Engineering High-Strength Aluminum Tubing Bundles (elsewhere in our catalog) maximizes the economy of scale for your shipping costs.
