What effect can strong signals from nearby transmitters have on an antenna analyzer?
Desensitization which can cause intermodulation products which interfere with impedance readings
Received power that interferes with SWR readings✓Richtige Antwort
Generation of harmonics which interfere with frequency readings
All these choices are correct
Erklärung
The analyzer measures the total RF voltage at its port, and it cannot distinguish its own low-power test signal from a strong signal arriving down the feed line from a nearby transmitter. That extra received power adds to the detected level and corrupts the impedance and SWR readings.
