Why Ladder Line?
RG-213 shop-bought at considerable expense; radiates RF when mismatched, typical loss: 4.8dB / 100m @ 30MHz. Ladder line: Easily constructed for a few cents per meter; radiates very little RF even when severely mismatched; typical loss: 0.33dB / 100m @ 30MHz
A Transmission line calculator
This transmission line calculator calculates the impedance at input and attenuation of a given transmission line once terminated with the given load
Coax Cable Loss calculator
Coaxial Cable Attenuation Loss Calculator in dB
Coax Impedance Calculator
Coaxial Cable Impedance Calculator allows you to enter the Outer Diameter Dielectric width, Inner conductor Diameter width and either the Dielectric Constant
Transmission Lines calculator
Calculates the resistance, inductance and capacitance per unit length of common low-loss transmission line configurations
