|The Worlds most popular SWR/RF analyzer just got
incredibly better and gives you more value than ever!
MFJ-259B gives you a complete picture of your antennas
performance. You can read antenna SWR and Complex Impedance
from 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
Heres 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. Youll 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 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!
