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.
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.
