How much improvement can I expect using Litz wire to wind a AM ferrite Rod antenna as opposed to using solid copper wire? Is it worth the trouble to obtain Litz wire, or can I expect almost the same response at say 1 MHz using regular enamaled copper wire? -Bill Bill, to give you a better background so the answer is more understandable is to think about what Litz wire does for you. When are delving into lower frequencies than AM then the skin depth required of the wire is much deeper that at higher frequencies and if the wire diameter is relatively small then the resistance goes up because even if there was enough skin depth the circumference is small. If the wire was made of many strands insulated from each other then the resistance goes down since the wires are in parallel. As I stated earlier Litz wire is used below AM frequencies. So now let us examine what wire resistance does at A.M. frequencies say on your auto, do you think that you could tell the difference on the radio if you replace the stainless whip with say a copper wire? No I don't think so. So for starters the Litz wire is not relavent for your frequency of use and 2 the conductivity of the whip will not affect your radios performance unless you took liberties with the conductivity and replaced your whip with a wooden stick Art |
