Information from MFJ Website (no accessories are included...only what I've itemized above):
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:
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
Tuned Circuits: Resonant frequency
RF chokes and inductors: Self resonance, series resonance, value
Transmitters and oscillators: Frequency
