This is an antenna analyzer for ham radio hobbyists. It can measure 50 ohms source impedance. It is also a meter for measuring SWR, impedance, capacitance...

Test the antenna technical parameters.
Can test the standing wave, impedance, capacitance and so on.
Frequency generation & control: 1-60MHz.
External power supply: 2.1mm power jack(center pin positive).
6 operation buttons, easy and convenient to operate.
Installed black metal case, just connect the power(not included) and then work.
Step size: user configurable increments of 100Hz, 1KHz, 10KHz, and 100KHz.
Support measuring data waveform analysis via connecting computer with USB cable(not included).

Instrument Capabilities:
Measure antenna electrical parameters: SWR, impedance(resistance+reactance), capacitance, inductance;
Measure feed point impedance;
Measure ground loss;
Adjust antenna tuners and determine loss;
Measure inductors and capacitors;
Measure coax transmission line(SWR, length, velocity factor, approximate Q and loss, resonant frequency, and impedance);
Measure and determine optimum settings for tuning stubs: SWR, approximate Q, resonant frequency, bandwidth, impedance;
Determine characteristic impedance of transmission line;
Determine length of ¼ and ½ wave phasing lines;
Coaxial Cable Loss; 
Determine antenna tuner loss;  
Measure balun loss;
Measure inductor Q; 
Estimate quartz crystal parameters;

Where is the software??

  • You need to download it. The software for the sark 100 works with the 300

Does the blue tooth connect to android phone or tablet? is there an app like the mini60?

  • Unknown. I do not use that feature.

    By Miriam Morgan-Alexander on January 7, 2018


Is it testing the uhf &vhf or only the hf ??

Did anyone's analyzer arrive calibrated? Mine did not and I'm not sure how to calibrate it. Without calibration, it's virtually useless.

  • Shouldn't need calibration. I checked mine against a Rigexpert that I borrowed from my brother, and it was very close. I am satisfied.

    Works fine for my needs. I needed a low power way to test swr. This unit does so quick and well. You can't go wrong!
