This is my second do it yourself coil. I activate parks regularly for the POTA and WWFF programs and this is my main goto antenna. Total number of turns of stainless wire is 104 which uses up the majority of the 15 metre length. Main parts list: -All threaded poly riser, 300mm x 40mm (1.5 inch). Search the internet for best price. -1.5 inch cap, threaded (Philmac brand) item number 4814101. Available at Bunnings hardware. -Stainless steel T-bolt hose clamp (44.5 - brand EnduraSeal) item number 0110772. Available at Bunnings hardware. -Tie wire stainless steel grade 304, x 15 metres (brand Whites). Available at Bunnings hardware. *Update …. A few comments from U.S. based ham’s have not found a U.S. domestic supplier for the threaded riser and end caps. If you would like to build you own then other ways of doing it are described in these videos:
