RF Cable Loss Calculator

This RF Cable Loss calculator determines the loss in coaxial cables. The formula used in this calculator is also explained below.

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:

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.
