The Worlds most popular SWR/RF analyzer just got incredibly better and gives
you more value than ever!
The new MFJ-259D has all the
features of the MFJ-259C Plus expanded frequency coverage.
The MFJ-259D now covers 100-160
KHz - 280-520KHz - 530KHz-230MHz
-
MFJ-259D gives you a complete pictures
of your antennas performance.
-
You can read antenna SWR and Complex
Impedance.
-
Read Complex Impedance as series
resistance and reactance (R+jX) or as magnitude (Z) and phase (degrees).
-
You can determine velocity factor, coax
cable loss in dB, length of coax and distance to a short or open in feet.
-
You can read SWR, return loss and
reflection coefficient at any frequency simultaneously at a single glance.
-
Also 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-Cad charger circuit, battery saver, low battery warning and smooth reduction
drive tuning and much more.

Super easy to use! Just set the band switch and tune the dial -- just like you
transceiver. SWR and Complex Impedance are displayed instantly!
Here's what you can do
-
Find your antennas true resonant
frequency.
-
Trim dipoles and verticals.
-
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 antennas 2:1 SWR bandwidth
on one band, or analyze multiband performance from 530 KHz to 230 Mhz!
-
Check SWR outside the ham bands without
violating FCC rules.
-
Take the guesswork out of building and
adjusting matching networks and baluns.
-
Measure distance in feet to a short or
open in faulty coax.
-
Measure length of a roll of coax, coax
loss, velocity factor, impedance.
-
Measure inductance and capacitance.
-
Measure resonant frequency and
approximate 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!
the MFJ-259D is a complete ham radio test station including -- frequency
counter, RF signal generator, SWR Analyzer, RF resistance and Reactance
Analyzer, Coax Analyzer, Capacitance and Inductance Meter and more!
Take it Anywhere!
-
Fully portable, take it anywhere -- remote sites, up towers, on DX-peditions.
-
Use 10AA or Ni-Cad
batteries (not included) or 110VAC with MFJ-1312D, (also not included).
I have these in stock if you need one.
-
Rugged all metal cabinet is only 4x2x6 3/4 Inches.
