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.
To use the calculator, follow these steps:
Enter Attenuation (dB): Input the attenuation if known. For example, enter 5
.
Enter Attenuation Constant (α): Input the constant if known. For example, enter 0.2
.
Enter Length (m): Input the length of the cable. For example, enter 100
.
The formula for calculating attenuation is:
Variables
Variable | Description |
---|---|
Attenuation (dB) | Signal loss in decibels |
Attenuation Constant ( | Rate of signal loss per meter |
Length (m) | Length of the cable in meters |
Example 1
Input:
Attenuation Constant
α=0.3
Length = 150 meters
Calculation:
Use the formula:
Calculate the exponent:
Convert to decibels:
Result: Attenuation is calculated in dB.
Example 2
Input:
Attenuation = 8 dB,
Length = 200 meters
Calculation:
Rearrange the formula to solve for
Calculate the attenuation constant:
