    I listed this a while back but missed the replies.
    Sorry
    Anyway, here it is again




    Selling a fully functional MFJ-259B with neoprene case.
    Shows signs of use, but not abuse.

    I will ship it to you via insured USPS Priority mail for $175.00
    Paypal is quickest.

    Let me know if you have questions.


    The MFJ-259B RF analyzer is a compact battery powered RF impedance analyzer. This unit combines four basic

    circuits; a 1.8-170 MHz variable frequency oscillator, a frequency counter, a 50 ohm RF bridge, and an eight-bit

    micro-controller. This unit makes a wide variety of useful antenna or impedance measurements, including

    coaxial cable loss and distance to an open or short.


    Primarily designed for analyzing 50 ohm antenna and transmission line systems, the MFJ-259B also measures RF

    impedances between a few ohms and several hundred ohms. It also functions as a signal source and frequency

    counter. The frequency range of impedance measurement is 1.8 to 170 MHz, in six overlapping bands.


    Typical Uses

    The MFJ-259B can be used to adjust, test, or measure the following:

    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

    Tuned Circuits: ..........................Resonant frequency and approximate Q

    Small capacitors:........................Value and self-resonant frequency

    RF chokes and inductors: ..........Self-resonant IMG_5721.JPG IMG_5721.JPG View attachment 499475 IMG_5720.JPG IMG_5722.JPG IMG_5723.JPG IMG_5724.JPG IMG_5725.JPG IMG_5726.JPG frequency, series resonance, and value

    Transmitters and oscillators:......Frequency

    The MFJ-259B measures and displays the following:

    Cable length (feet) Impedance phase (degrees) Resonance (MHz)

    Cable Loss (dB) Inductance (uH) Return loss (dB)

    Capacitance (pF) Reactance or X (ohms) Signal Frequency (MHz)

    Impedance or Z magnitude (ohms) Resistance or R (ohms) SWR (referenced to 50 ohms)

    The MFJ-259B is useful as a non-precision signal source. It provides a relatively pure (harmonics better

    than -25 dBf) signal of approximately 3 Vpp (approximately 20 milliwatts) into 50 ohm loads. The MFJ-259B

    internal source impedance is 50 ohms.
