MFJ-259C World’s Most Popular Analyzer
MFJ-259C now covers a super wide range -- 530 KHz to 230 MHz -- no gaps!
It is super easy to use! Just set the bandswitch and tune -- just like your transceiver. SWR, Complex antenna Impedance and frequency are all instantly displayed simultaneously! MFJ-259C gives you complete picture of your antenna.
Read SWR, return loss and reflection coefficient at any frequency all at once.
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 in feet. Measure inductance in uH and capacitance in pF at actual operating frequencies. It’s an all-in-one ham radio test set
Includes frequency counter, RF Generator, SWR Analyzer™, RF Resistance and Reactance Analyzer, Coax Analyzer, Capacitance and Inductance Meter and more! Large easy-to-read two line LCD screen and side-by-side meters clearly display your information.
Here’s what you can do . . .
Find your antenna’s true resonant frequency. Trim dipoles and verticals for lowest SWR at your favorite frequencies. Adjust your Yagi, quad, loop and other antennas, change antenna spacing and height and watch SWR, resistance and reactance change instantly. You’ll know exactly what to do by simply watching the displays.
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 and analyze multiband performance! Check SWR outside ham bands without transmitting and violating FCC rules. Adjust your antenna tuner for a perfect 1:1 match without creating QRM. Take the guesswork out of building and adjusting matching networks and baluns and antennas.
Accurately measure distance to short or open in failed coax. Measure coax length in feet, loss in dB, velocity factor and impedance.
Measure inductance, capacitance and troubleshoot and measure resonant frequency, Q of traps, stubs, transmission lines, RF chokes, tuned circuits and baluns.
Lower band can be retuned to cover 470 to 940 KHz for maritime and 600 Meter bands.
Built-in Ni-MH/Ni-CD charger circuit, battery saver, low battery warning and smooth reduction drive tuning. Use 10 AA or Ni-MH batteries (not included) or 110-240 VAC with optional MFJ-1312D, $15.95. Rugged, compact all-aluminum construction, 4Wx63/4Hx2D inches.
New! MFJ-259C, $299.95.
Maritime and 600 Meter Coverage Analyzer
MFJ-259CM is like the popular MFJ-259C except the bottom band covers 470-940 KHz for Maritime and 600 Meter bands.
New! MFJ-259CM, $299.95.
