What is Coaxial Cable Attenuation?

Coaxial cable attenuation refers to the loss of signal strength as it travels through the cable. This loss depends on the length and the attenuation constant.

How to calculate Coaxial Cable Attenuation

How to Use the Calculator

To use the calculator, follow these steps:

  1. Enter Attenuation (dB): Input the attenuation if known. For example, enter 5.

  2. Enter Attenuation Constant (α): Input the constant if known. For example, enter 0.2.

  3. Enter Length (m): Input the length of the cable. For example, enter 100.

Formula

The formula for calculating attenuation is:

Attenuation (dB)=10×log10(e2×α×Length)

Variables

Variable Description
Attenuation (dB) Signal loss in decibels
Attenuation Constant ( α 0 Rate of signal loss per meter
Length (m) Length of the cable in meters

How to Calculate?

Example 1

Input:

Attenuation Constant

α=0.3

Length = 150 meters

Calculation:

Use the formula:

Attenuation=10×log10(e2×0.3×150)

Calculate the exponent: e90

Convert to decibels:

10×log10(e90)

Result: Attenuation is calculated in dB.

Example 2

Input:

Attenuation = 8 dB,

Length = 200 meters

Calculation:

Rearrange the formula to solve for

α=log(10810)2×200

Calculate the attenuation constant:

αcalculated value
