MFJ 249B Antenna Analyzer HF to 2 Meters and CB
The World's most popular SWR analyzer just got incredibly better and gives you
more value than ever! The MFJ-249B 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). 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 your
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. 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.
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!
Rugged all metal cabinet is only 4 x 2 x 6-3/4 inches.
Uses 10AA or Ni-Cad batteries (not included) or 110VAC with MFJ-1312D.
All readings display on LCD, no meters on this model!
