Also, most of the time the RF voltage measurement is made on a "sampled" signal via a coupler. This allows the coax to have a straight-line through to the load (Antenna) with very little loss. Since it is sampled via a coupler, you would need to calibrate the voltage readings which usually requires another quality lab style RF voltmeter. – K7PEH.

An RF receiver typically consists of four main blocks: the antenna, the RF amplifier, the mixer, and the demodulator. The antenna is used to receive the RF signal and convert it to an electrical signal. The RF amplifier is used to amplify the signal before it is mixed with a local oscillator (LO) signal in the mixer. The analog output on the receiver module (Received Signal Strength Indicator (RSSI) pin 3) can be connected to an ADC and used as a rough indicator of signal strength whenever the receiver is locked on an RF signal. To be useful, it needs to be read only during signal transmissions. When there is no signal present it will still be a bit high.
