What is the consequence of a badly matched antenna for the output device?
Answer: C
A mismatch reflects power back into the stage, raising the voltage and current it must withstand and heating it, which is why protection circuits monitor the standing wave ratio and reduce power. The oscillator is buffered from the load, so no drift follows. Modulation depth is set upstream. And the filter continues to work, though the reflected energy passes through it twice. Following a fault through to the component that suffers is the practical value of the concept.
