Q = Xl / R = Inductive_reactance / Resistance_and_losses Assuming the inductance remains the same, changing the style of the inductor, such as a ferrite core, loop antenna, Litz wire, scramble wound solenoid, or honeycomb basketweave, will not change the inductive reactance. Only the resistive and other losses part dissipates power. Any change in Q will involve the resistive part of the puzzle. For example, switching from magnet wire to Litz wire offers an increase in surface area. Since RF conduction occurs on the wire surface (skin effect), and Litz wire has a larger surface area, the Q will be higher. A receiver design that doesn't over-load the coil, where the losses from the load across the coil is substantially greater than the dissipative losses from the coil resistance and surface area, should be able to benefit from the increase Q by recovering more power. Whether this appears as an increase in voltage or current depends on how the power is "tapped" from the coil. <https://en.wikipedia.org/wiki/Litz_wire> "The ratio of distributed inductance to distributed resistance is increased, relative to a solid conductor, resulting in a higher Q factor at these frequencies." I guess I should mention that Litz wire works well up to about 1MHz. At higher frequencies, the eddy currents in the inside windings form, creating additional losses which negate the benefits of using Litz wire. -- Jeff Liebermann jeffl@cruzio.com 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558
