The
World's most popular SWR/RF analyzer just
got incredibly better and givesyou more
value than ever!MFJ-259B gives you a
complete pictures of your antenna's
performance. You canread antenna SWR and
Complex Impedance 1.8 to 170MHzRead
Complex Impedance as series resistance and
reactance (R+jX) or asmagnitude (Z) and
phase (degrees). You can determine
velocity factor, coaxcable loss in dB,
length of coax and distance to a short or
open in feet. Youcan read SWR, return loss
and reflection coefficient at any
frequencysimultaneously at a single glance.
Also read inductance in UH and
capacitancein pF at RF frequencies. Large
easy-to-read two line LCD screen
andside-by-side meters clearly display
your information. Built-in
frequencycounter, Ni-Cad charger circuit,
battery saver, low battery warning and
smoothre-duction drive tuning and much
more. Super easy to use! Just set
thebandswitch and tune the dial -- just
like you transceiver. SWR and
ComplexImpedance are displayed instantly!Here's
what you can doFind your antenna's true
resonant frequency. Trim dipoles and
verticals.Adjust your Yagi, quad, loop and
other antennas, change antenna spacing
andheight and watch SWR, resistance and
reactance change instantly. You'll
knowexactly what to do by simply watching
the display. Perfectly tune critical
HFmobile antennas in seconds for super DX
-- without subjecting your transceiverto
high SWR. Measure your antenna's 2:1 SWR
bandwidth on one band, or analyzemultiband
performance from 1.8 to 170Mhz! Check SWR
outside the ham bandswithout violating FCC
rules. Take the guesswork out of building
and adjustingmatching networks and baluns.
Measure distance in feet to a short or
open infaulty coax. Measure length of a
roll of coax, coax loss, velocity factor,impedance.
Measure inductance and capacitance.
measure resonant frequency andapproximate
Q of traps, stubs, transmission lines, RF
chokes, tuned circuitsand baluns. Adjust
your antenna tuner for a perfect 1:1 match
without creatingQRM. And this is only the
beginning! the MFJ-259B is a complete ham
radio teststation including -- frequency
counter, RF signal generator, SWR Analyzer,
RFresistance and Reactance Analyzer, Coax
Analyzer, Capacitance and InductanceMeter
and more! |

Covers
1.8 to 170 MHz and 415 to 470 MHz -- an
MFJ-269 Exclusive! It includesall the
features of the MFJ-259B, the world's most
popular SWR Analyzer plusmuch more! Large
easy-to-read two line LCD display and
side-by-side metersclearly display your
information Built-in Ni-Cad/Ni-MH charger
circuit, batterysaver, low battery warning,
smooth reduction drive tuning. Use as
signal sourcefor testing/alignment.
Built-in CoaxCalculator -- calculates coax
line lengthin feet given coax length in
electrical degrees and vice versa for
anyfrequency and any velocity factor (great
for building matching sections andphasing
lines) -- an MFJ-269 Exclusive! New 12-bit
A/D converter gives muchbetter accuracy
and resolution than common 8-bit A/D
converters -- an MFJ-269exclusive. Super
easy to use! Just set the bandswitch and
tune the dial -- justlike you
transceiver.1.8 to 170MHz range
featuresMFJ-269 gives you a complete
picture of you antenna. Read antenna SWR
andComplex Impedance 1.8 - 170 MHz. Built
in frequency counter. Read
ComplexImpedance as series equivalent
resistance and reactance (Rs+jXs) or
asmagnitude (Z) and phase (degrees). Also
read parallel equivalent resistance
andreactance (Rp+jXp) -- and MFJ-269
exclusive! You can determine velocity
factor,coax loss in dB, length of coax and
distance to short or open in feet. You
canread SWR, return loss and reflection
coefficient at at any
frequencysimultaneously at a single glance.
Also read match efficiency. Also
readinductance in UH and capacitance in pF
at RF frequencies. You can measure SWRand
loss of coax with any characteristic
impedance from 10 to over 600 Ohms,including
50, 51, 52, 53, 73, 75, 93, 95, 300, 450
Ohms -- an MFJ-269exclusive! For more
information see MFJ-259B. New 415 to 470
MHz Rangefeatures. Just plug in your UHF
antenna coax, set the frequency and read
SWR,return loss and reflection coefficient
simultaneously. You can read coax
cableloss in dB and match efficiency.You
can test and tune stubs and coax lines.
You can manually determine velocityfactor
and impedances of transmission lines. You
can adjust and test RFmatching networks
and RF amplifiers without applying power.
Has easy-to-readLCD logarithmic SWR
bargraph and SWR meter for quick tuning.Take
it anywhereFully portable take it anywhere
-- remote sites, up towers, on
DX-peditions.Built in "N"
connector Free N-to-SO-239 adaptor. Use
