Try an electrical wholesaler, though it is likely annealed, not hard drawn.
Also www.mscdirect.com for "Copper Ground Wire" they have 10, 8 & 6 AWG
solid, but in long spools ~$100 each.

I'm trying to complete an antenna project and was wondering if anyone knew
of a source for bare, solid copper #10 AWG.

Thanks in advance,
