“Can I use a field strength meter to measure the power of a transmitter? How do I do that?"

 

Field strength meters measure the strength of the signal that is emitted by an antenna. Although it has a relationship with the power of the transmitter, they do not indicate it in absolute terms. So, we use it to measure the efficiency of the antenna. We can get an idea of the power of a transmitter if we compare the signal emitted with a transmitter of known power with one of unknown power at the same point.
