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.

This MFJ Starter SWR Analyzer lets you read SWR from 1,8 to 170 MHz quickly only on a single analog meter. Tune knob, frequency control switch. No LCD module, counter or charging circuit. Use 10 AAcells or 110 VAC with MFJ-1312DX.

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 1,8-170 MHz. 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 6 ranges.

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
