Hi I’m looking for some guidance in finding some of these parts:
- 1 Pcs Aluminium (Square tubes profile 20x20mm) = 1600mm
- 2 Pcs Aluminium (Symmetrical L profiles 15x15mm or 20x20mm) = 680mm
- 2 Pcs Aluminium (Symmetrical L profiles 15x15mm or 20x20mm) = 420mm
- 1 pc at least of 70Χ70cm good quality grid mesh of 2mm with at 1in (25,4 mm) spaces.
I haven’t had much luck with google searching, and was wondering if any of you who have successfully made this version of the helical can recommend a source for ordering metric size parts in America. I have tried a site called metric metals but they do not stock the L profiles. If theres any successful imperial measured substitution I am also open to that.
I have no luck whatsoever finding the grid mesh, and additionally, what type of metal should be used for it?
Also why is the antenna using brass as opposed to copper/aluminum. Sorry if these questions seem redundant.
