MFJ-259C by MFJ Enterprises, Inc.


The MFJ-259C is the world’s most popular SWR Analyzer combining many essential circuits in a compact size!

More details

The MFJ-259C is a compact, battery-powered RF impedance analyzer that combines 4 basic circuits:
  1. Variable Frequency Oscillator
  2. Frequency Counter
  3. 50-ohm RF-Bridge
  4. 8-bit A/D Converter and Microcontroller

Together, these circuits perform a wide variety of useful antenna and RF impedance measurements including coaxial cable loss and electrical distance to an open or short.

MFJ-259C has two frequency-range knobs to allow wider control. The new lower-frequency coverage allows analysis of 160 meter antennas as well as MW (AM broadcast) and other shortwave frequencies. The extended coverage to include the 220 MHz band is another very worthwhile addition!

  • Built-in frequency counter, Ni-MH/Ni-Cad charger circuit, battery saver, low battery warning and smooth reduction drive tuning
  • Large, easy-to-read, 2-line LCD screen and side-by-side meters display your information clearly
  • The MFJ-259C also functions as a non-precision signal source and frequency counter
  • Operating frequency extends from .53 to 230MHz in several overlapping bands
  • Use the versatile MFJ-259C to test:
    • Antennas: SWR, impedance, reactance, resistance, resonant frequency, and bandwidth
    • Antenna Tuners: SWR, bandwidth, frequency
    • Amplifiers: input and output matching networks, chokes, suppressors, traps, and components
    • Coaxial Transmission Lines: SWR, length, velocity factor, approximate Q and loss, resonant frequency, and impedance
    • Filters: SWR, attenuation, and frequency range
    • Matching or Tuning Stubs: SWR, approximate Q, resonant frequency, bandwidth, impedance
    • Traps: Resonant frequency and approximate Q
    • Tunes Circuits: Resonant frequency and approximate Q
    • Small Capacitors: Value and self-resonant frequency

Size: 4” x 2” x 6.75” (W x D x H).

Require 10 AA-size batteries for portable operation (not included).
