The calculator converts from radiated power in dBuV/m (deciBel microvolt-per-meter) at 3 meters to conducted power in dBm at the output of the transmitter.
In this example we compute the maximum transmitter power in dBm from the level of the radiated field 3 meters away.
500 uV/m equates to 54 dBuV/m.
A field strength value of 54 dBuV/m equates to a power level of -41.2 dBm at the transmitter.
Output Power of Wholehouse FM Transmitter
I was trying to figure out the output transmit power of the Whole House FM transmitter.
The FCC report shows a maximum average level of 41.42 dBuV in the FM band. This translates to -53.78 dBm at the output of the FM transmitter.
