Disclaimer: The Java applet and windows versions of the PI Network calculators are still somewhat experimental. Calculations have been made and compared to some of the table values in the 1996 ARRL Radio Amateur's Handbook and tested on my "BTA-500R Transmitter Project" PI network with good results. No guarantees are offered!
(Single layer winding, #12 bare wire)
Use in either of two ways: To calculate inductance, fill in Number of Turns, Diameter and Length boxes, then click "Calc. L" button. To calculate Number of turns, fill in Inductance in uH, Diameter and Length boxes, then click "Calc. Turns" button.
(Windows version is included as a subdialog of the PI Network Windows calculator)
