Money rears it's head as an issue, aluminum is cheaper. +1 for aluminum. Resistivity is 65% higher for aluminum. I'd give that a -1, however, if maximizing Q is not important in your design then still at +1. Oxidation: Copper oxide vs Aluminum oxide. Aluminum oxide is an insulator. How does that affect skin resistance? I don't know, does it just shrink your tubing by the thickness of the oxide? Copper oxide is said to be a semiconductor, has much, much lower resistance than aluminum oxide. Page 5, http://www.ets-lindgren.com/pdf/emctd_1293_weibler.pdf Or just varnish it. Bottom of page, http://hamwaves.com/coils/en/ Aluminum is a great material to work with. My magloop nightmare come true: http://www.mixw.co.uk/MagLoop/magloopF.htm I don't get your point here. Build one, monitor your dreams. Jeff, I don't like the parallel sections, seems like it could be made more complicated using x, y, and z right angles. Nap on that! :-) Mikek |
