MFJ-259C 530 KHz - 230 MHz SWR Analyzer
World’s most popular SWR analyzer is super easy-to-use
The famous MFJ-259C gives you a complete picture of your
antenna’s performance. You can read your antenna’s SWR and
Complex Impedance 530 KHz to 230 MHz continuously with no
You can read Complex Impedance as series resistance and
reactance (R+jX) or as magnitude (Z) and phase (degrees).
Determine velocity factor, coax loss in dB, coax length and
distance to a short/open.
Read SWR, return loss and reflection coefficient at any
You can read inductance in uH and capacitance in pF at RF
Large easy-to-read two line LCD screen and side-by-side
analog meters clearly display your information.
Built-in frequency counter, Ni-MH/Ni-CD charger circuit,
battery saver, low battery warning and smooth reduction
Super easy to use! Just set the band switch and tune the
dial -- just like your transceiver. SWR and Complex
Impedance are displayed instantly!
Here’s what you can do
Find your antenna’s true resonant frequency. Trim dipoles
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 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.
Check SWR outside the ham bands without violating FCC rules.
Take guesswork out of building and adjusting matching
networks and baluns.
Accurately measure distance to short or open in failed coax.
Measure length of a roll of coax, coax loss, velocity factor
Measure inductance, capacitance. Troubleshoot and measure
resonant frequency, Q of traps, stubs, transmission lines,
chokes, tuned circuits, baluns.
Adjust your antenna tuner for a perfect 1:1 match without
MFJ-259C is a complete ham radio test station with frequency
counter, RF signal generator, SWR/Resistance/Reactance/Coax
Analyzer, Capacitance/Inductance Meter and much more!
