Longwave coils
WebLow frequency (LF) is the ITU designation for radio frequencies (RF) in the range of 30–300 kHz.Since its wavelengths range from 10–1 km, respectively, it is also known as the kilometre band or kilometre wave. LF radio waves exhibit low signal attenuation, making them suitable for long-distance communications.In Europe and areas of Northern Africa … Web0.4 mm diameter enamelled copper wire was used for all windings. This diameter is not particularly critical, but 0.4 mm is easy to work with but still results in fairly compact coils. …
