New program. COAXTUNE.exe
A 1/4-wave coaxial line, short-circuit at one end, behaves as a screened LCR tuned circuit. A line less than
1/4-wavelength, in parallel with a variable capacitor, behaves as an adjustable tuned circuit.For given line length, inner and outer diameters, the program calculates the value of the tuning capacitor needed to resonate the circuit at any frequency from LF to microwaves. Included in results are line input resistance at resonance, input reactance (which is tuned out by the capacitor), Q and bandwidth. Along with other characteristics of the line such as Zo and attenuation.
