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.
