Digital MR300 Antenna Analyzer Shortwave Meter Tester SWR For Ham Radio Black. Note : the item is not inclued Built-in battery, Does not support Bluetooth! 100% Brand New & High Quality.

Radio enthusiasts an essential tool for entry. Test the antenna technical parameters. Can test the standing wave, impedance, capacitance and so on. Can be connected to the computer to do antenna and other graphic analysis. Power supply: External: 13.8 to 19 Volts DC, 500mA; Internal: 8xAAA 1000mAh NiMH cells. Charging time: 12 hours (charge rate 0.1C). Measure antenna electrical parameters: SWR, impedance (resistance + reactance), capacitance, inductance. 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. Power requirements: within the positive external. 12V - Driveable talent works, but can not charge the battery. 3.8V 18V - can drive the talent to work normally, can also be normal for the battery charge. Frequency Generation & Control: 1 - 60 Mhz. Spectral Purity: Harmonics down Greater than - TBD dB beyond 60 MHz. Step Size: User configurable increments of 100 Hz, 1 kHz, 10 kHz, and 100 kHz. SWR: 1.0 to 9.99. RF Output: Adjustable: 2.0 Volts pp (typ). Pushbuttons (5): "Mode", "Band", "Config", "Scan", "Up", "Down". External power: 2.1mm Power Jack (center pin positive). Measure ground loss: Adjust antenna tuners and determine loss.

Determine characteristic impedance of transmission line. Determine length of ¼ and ½ wave phasing lines. 1PCMR300 Digital Shortwave Antenna Analyzer Meter Tester. Because of the airspace controls.
