MFJ 921

MFJ-921 Dual Band VHF tuner covers 2 Meters/220 MHz.

Built-in SWR/Wattmeter measures SWR in 2 power ranges: 300 or 30 Watts. Meter is usable for both 144 MHz and 220 MHz bands. Low SWR with practically any antenna. Handles 200 Watts. Designed to match a wide range of impedances for both mobile/base operation. SO-239 input/output connectors, wing nut post ground. Black aluminum cabinet measures a compact 8 x 2 1/2 x 3 inches — fits just about anywhere.

MFJ 259B



Spesifikasi :
The MFJ-259B SWR analyzer features a built-in 10 digit
high-contrast LCD frequency counter. Reading your
antennas SWR and finding its resonance has never
been easier. All you do is connect your antenna, set
your SWR analyzer to the frequency you want and
read your SWR.MFJ-259B gives you a complete
pictures of your antenna’s performance. You can read
antenna SWR and Complex Impedance 1.8 to 170 MHz.
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. The large
easy-to-read two line LCD screen and side-by-side
meters clearly display your information. The built-in
frequency counter, Ni-Cad charger circuit, battery saver,
low battery warning and smooth reduction drive tuning
and much more. The MFJ-259B is easy to use! Just set
the bandswitch and tune the dial – just like you transceiver.
SWR and complex Impedance are displayed instantly!
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
