Bend Attenuation Solution

Follow our step by step solution on how to calculate Bend Attenuation?

FIRST Step Consider the formula

α b = 10 \cdot \log 10 (\frac{P s}{P b})

Next Step Substitute values of Variables

∴

α b = 10 \cdot \log 10 (\frac{5.5W}{3.5W})

Next Step Prepare to Evaluate

∴

α b = 10 \cdot \log 10 (\frac{5.5}{3.5})

Next Step Evaluate

∴

α b = 1.96294645143968dB/m

LAST Step Rounding Answer

∴

α b = 1.9629dB/m
