Product Description
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.
