Where should an RF power meter be installed?

An RF power meter measures the Radio Frequency energy that your transceiver generates to send out over the airwaves. Because this RF energy travels along the coaxial cable from the radio to the antenna, the meter must be connected directly in series within that path (the feed line). Placing the meter at the power supply output or in the power supply cable would measure the DC power consumed by the radio, not the RF power it produces. Connecting it in parallel is also incorrect, as RF power meters are flow-through devices that must be placed directly in line with the signal path.
