MFJ 259 Antenna Analyzer with SWR & Impedance Meters
The World's most popular SWR/RF analyzer just got incredibly better and gives
you more value than ever!
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! 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!
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, 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,
