product description:
Read your antenna s SWR and Complex Impedance 530 KHz to 230 MHz. Read Complex Impedance as series resistance and reactance (R+jX) or as magnitude (Z) and phase (degrees). Determine velocity factor, coax cable loss in dB, length of coax and distance to a short or open. Read SWR, return loss and reflection coefficient at any frequency simultaneously. Read inductance in uH and capacitance in pF at RF frequencies. Large easy-to-read two line LCD screen and side-by-side meters clearly display your information. Built-in frequency counter, Ni-MH/Ni- CD charger circuit, battery saver, low battery warning and smooth reduction drive tuning. Just set the bandswitch and tune the dial -- just like your transceiver. SWR & Complex Impedance are displayed instantly! Find your antenna s true resonant frequency. Trim dipoles and verticals. Adjust your Yagi, quad, loop & other antennas, change antenna spacing & height and watch SWR, resistance and reactance change instantly. You ll know exactly what to do by simply watching the display. Perfectly tune critical HF mobile antennas in seconds for super DX -- without subjecting your transceiver to high SWR. Measure your antenna s 2:1 SWR bandwidth on one band, or analyze multiband performance from 530 KHz to HF to VHF -- 530 KHz -230 MHz! Check SWR outside the ham bands without violating FCC rules. Accurately measure distance to short or open in failed coax. Measure length of a roll of coax, coax loss, velocity factor & impedance. Measure inductance, capacitance. Troubleshoot and measure resonant frequency & Q of traps, stubs, transmission lines, RF chokes, tuned circuits and baluns. Adjust your antenna tuner for a perfect 1:1 match without creating QRM. And this is only the beginning! MFJ- 259C is a complete ham radio test station including -- freq counter, RF signal generator, SWR AnalyzerTM, RF Resistance & Reactance Analyzer, Coax Analyzer, Capacitance & Inductance Meter & more!
