OUTPUTS: RF Cable Loss = 6.93 dB/100ft, 10.4 dB/150 ft

Formula/Equation used in RF Cable Loss calculator

Following formula/equation is used in this RF cable loss calculator.

rf cable loss formula

The cable Loss consists of conductor wire loss, insulation loss and connector loss. As mentioned in the equation, conductor loss (K1) relates to square root of frequency, insulation loss (K2) relates to frequency and connector loss relates to connectors used in the cable. Connectors can be either straight type or right angled type.
