MFJ-259B Manual
The World's most popular SWR/RF analyzer just got incredibly better and
gives you more value than ever!
MFJ-259B gives you a complete pictures of your antenna's performance. You can
read antenna SWR and Complex Impedance 1.8 to 170MHz
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 re-duction drive tuning
and much more. Super easy to use! Just set the bandswitch and tune the dial --
just like you transceiver. SWR and Complex Impedance are displayed instantly!
Here's what you can do
Find your antenna's 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 antenna's 2:1 SWR bandwidth on one band, or analyze
multiband performance from 1.8 to 170Mhz! 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-259B 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. Rugged all metal cabinet is only 4x2x6 3/4 Inches.
