The MFJ 259 has measures many functions.
It measures just about all transmission line equation parameters and the 
alterations caused by loads - antennas.
Here's its parameter list and how to move to them.
In normal mode you have the starting parameters:
Impedance Frequency, R, X SWR
Press mode and the screen displays
coax loss
For each additional mode tap of the mode switch it measures
Coax Loss
Frequency Counter
and back to R,X,SWR,f.
Simultaneously press the mode and gate switches for a few seconds.
This enters you into the Advanced Mode.
Each tap of the mode switch offers:
Return Loss Coefficient
Distance to fault
Resonance mode tune
Match efficiency
Z Magnitude and angle
One finds this by pressing the buttons and see what occurs or
Goggle MFJ 259 manual and you'll find sources of the manual. I believe 
downloadable manuals.
Have fun,
