KE5RS Handy Calculators

Cable Characterization Calculator
Enter Measured Resonant Frequency, Capacitance and Cable Length
	Cable Length (feet)
	Resonant Frequency (MHz)
	Total Capacitance (pF)
	Impedance	= Propagation Delay / Capacitance
	Propagation Delay (nS/ft)	= 1 / Resonant Frequency
	Capacitance (pF/ft)	= Total Capacitance / Cable Length
	Inductance (uH/ft)	= (Impedance² Capacitance) / 1,000,000*
	Velocity of Propagation (%)	= Speed of Light / Propagation Delay

Coax Impedance Calculator
	Dielectric Constant
	Inch Center Conductor Diameter
	Inch Shield Inside Diameter
	Impedance
