Try HW #12 pure copper tube, not the alloy mix you get these days for commercial wiring and plumbing, even better SPT (silver plated tube tube) Gold plate tube even better, very low RAC. These are all easy to solder and although hard to get out perform all other varieties, available in all sizes from diameters barely visible to sizes that need a fork lift to move about. 73 de G3KEV > another with identical dimentions from #12 Litz to prove to you there is a > 2x reduction in Rac?
