Product Information
  • Overview
  • Measurements that can be made
The MFJ-269C is a compact battery powered RF impedance analyzer. It combines five basic circuits; a variable oscillator, frequency counter, frequency multiplier, 50-ohm RF bridge, twelve-bit A-D converter, and a 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.
Antennas:                                SWR, impedance, reactance, resistance, resonant frequency, and
Antenna tuners:                       SWR, bandwidth, frequency
Amplifiers:                               Input and output matching networks, chokes, suppressors, traps, and
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
Tuned Circuits:                        Resonant frequency and approximate Q
Small capacitors:                    Value and self-resonant frequency
RF chokes and inductors:         Self-resonant frequency, series resonance, and value
Transmitters and oscillators:    Frequency

  • Resonance (MHz)
  • Feedline Loss (dB)
  • Inductance (μH) Return loss (dB)
  • Capacitance (pF)
  • Reactance or X (ohms)
  • Signal Frequency (MHz)
  • Impedance or Z magnitude (ohms)
  • Resistance or R (ohms)
  • SWR (Zo programmable)
