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;

I bought one it appears to work ok, but where is the manual and the software for the computer, The MR300, does it have a web site???

  • Works great for me. You can find the software on line and the manual. Look for Sark100, controls are same and looks like the board is same just different case. I haven't needed the software so I didn't download it. No direct web site I could find but finally found a reference to the Mr300 in the Sark stuff.

Were do the AAA battery's go?

  • This model actually has no battery connection, all of that information seems to have been copied from the original kit version which did. You'll need to use the 2.1mm power jack. It's pretty tolerant of voltage, so you could connect it to a battery pack if necessary.

    By Raibeart on January 9, 2018


Does the mr300 come with the battery holder? i know it does not come with the aaa cells or charger. would i have to order a battery holder too?

  • I don’t think it comes with a battery holder, but I haven’t taken it apart to check.

    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!
