Copper is very expensive at this time. I'd go for galvanized mesh wire fencing [chicken wire?] .. quite inexpensive for a roll. Make sure it's WELDED BEFORE galvanize, ir the 'joints' will be 'diodes

Slight correction, Gene. The LPDA is at LEAST a two-element radiator. On some frequencies [at or near the mid-point of its design] it will approximate a three-element beam. This is because at least o

What you have is the OLD, light-duty Heights tower. Take all the sections to someone with TIG-welding know-how and get ALL the welds checked and redone INSIDE and OUT. Just a word to the wise. Don N8

Of greater concern is the moisture which might/WILL be trapped inside. If you can find some silica-gel pacs, put them inside BEFORE you do any 'sealing.' Don N8DE ____________________________________
