The reflected W beam
Please find on this page a collection of parts to build this or other antennas. If you are looking for a complete beam please send me a mail with the bands you would like to have included. As I'm not producing on stock it takes between 6-8 weeks to built a complete antenna. The offered materials are of high quality and tested under sunny and salt water conditions (tropical climate). We only use extremly strong, black fiberglas for the spreaders, a special thermo-plastic Polyurethane for the base plate, black PE, stainless steel or brass hardware and Kevlar or dark Dacron lines. I know that many of those parts are hard to get (if ever) because they are custom made on my needs. To get reasonal prices I often had to order big volumes and so I'm happy to offer some of those "hard to get" parts for homebrewers and hopefully can cover my own costs. For easy payment from outside Germany or Europe I recommend the use of a paypal account. Transportation costs have to be checked if I know delivering address and volume of the order (size & weight). All prices are in Euro. If only small pieces are ordered I try to send it in letter form to prevent you from custom questions.
The antenna has 6 spreaders, 1 base plate and 1 center mast. For each band you need: wire, 4 connectors to the center hub, 6 clamps, 4 end insulators, 4 messing screws (plus accessories).

Screws, nuts and washers made from brass (Messing)
