Simple to calibrate and accurate against professional spectrum analyzers.
Perfect for field use, compact and long battery life.
Reviewed in the United States on May 23, 2024
With the spectrum analyzer, I could see the whole spectrum at once and orient the antenna properly.
Never received so many channels before!
I'm now using it to track down noisy devices and energy vampires.
