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 clearly displays 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! 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, $14.95. Rugged
all metal cabinet is only 4x2x6 3/4 Inches.

All readings display on LCD,no meters on
this model.
