MFJ-259B
ist "der keine Bruder" von MFJ-269
und hat einen Frequenzbereich von 1,8 bis 170 MHz. Mit MFJ-259B
haben Sie ein "komplettes Abbild" Ihrer Antenne - weiter
mehr als nur eine einfache SWR-Messung. Für weitere Informationen
empfehlen wir auch die englische

One of the World's most popular SWR/RF
analyzer just got incredibly better and gives you more value than ever!
MFJ-259B 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). 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!
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! |
