Inputs

Outputs

EXAMPLE:

  • INPUTS: Frequency = 2500 MHz, K1 = 0.11694, K2 = 0.00036, CLF = 0.12, L = 150ft
  • OUTPUTS: RF Cable Loss = 6.93 dB/100ft, 10.4 dB/150 ft

RF Coaxial Cable Loss Formula

The following formula is used to calculate RF coaxial cable loss:

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) is related to the square root of the frequency.
  • Insulation loss (K2) is related to the frequency.
  • Connector loss is related to the connectors used in the cable. Connectors can be either straight type or right-angled type.
