I don't know if any one is interested, but I think I know a good material for antennas and wires. Besides modeling, another hobby of mine is fly tying (fishing). In fly fishing stores that sell fly tying supplies, they carry very, very small metal wires (they look like thread on a bobbin). It can be bent and shaped or just be straight. I havn't had the chance to try it out yet, hopefully soon. Fly tying stores also hold regular thread that is really small. Maybe it will help, maybe it won't.
