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

Dipole Antenna Calculator

Enter Frequency in KHz


Feet = Each leg of Dipole

Feet = Each leg of Inverted "V"
