Net Power defined as Forward Power minus the Reflected Power This document describes how you should calculate the Net power correctly.

**Given information**
Frequency (MHz)	Forward Power (dBm)	Reflected Power (dBm)
201,973	50	30

Question: What is the Net Power?

Answer: 141,8144768 mA

First you calculate the dB difference in power.

$35,4-35,1=0,3\ dB$

Calculate the calibrated current to dBmA so we can add the value.

$20*log10(137)\approx 42,73441134\ dBmA$

So after the addition of the power difference the new value is 43,03441134 dBmA.

Calculate this back to mA:

$10^{\frac {43,03441134}{20}}\approx 141,8144768\ mA$
