The MFJ-209 SWR Analyzer is an easy to operate, versatile test instrument for analyzing nearly any 50 ohm RF system on frequencies between 1.8 and 170 MHz. In addition the MFJ-209 can be used as signal source.

The MFJ-209 combines three basic circuits; a wide range oscillator, a 50 ohm RF bridge, and a calibrated bridge unbalance indicator. This combination of circuits allows measurement of the SWR (referenced to 50 ohms) of any load connected to the ANTENNA connector.

The MFJ-209 covers all ham bands from 2 meters to 160 meters. The dial calibration is approximate and for reference only. The actual frequency may vary from what is marked on the front panel. The MFJ-209 FREQUENCY switch selects the following frequency ranges:

1.8 - 4 MHz
4 - 10 MHz
10 - 26.2 MHz
26.2 - 62.5 MHz
62.5 - 113 MHz
113 - 170 MHz

A frequency counter can be connected to the "FREQ. OUT" jack (RCA phono) to get a more accurate reading of the frequency. As an alternative to a frequency counter, you can zero beat the output with an HF receiver. See the section on zero beating the MFJ-209 with a receiver.

The MFJ-209 can be used to adjust or measure the following:

Antennas : SWR, resonant frequency, bandwidth, efficiency
Antenna tuners : SWR, frequency
Amplifiers : Input and output networks
Coaxial transmission lines : SWR, velocity factor, losses, resonance
Balanced transmission lines : Impedance, velocity factor, resonance
Matching or tuning stubs : SWR, resonant frequency, bandwidth
Traps : Resonant frequency
Tuned Circuits : Resonant frequency
Small capacitors : Value
RF chokes and inductors : Self resonance, series resonance, value
Transmitters and oscillators : Frequency
