[RFI] RF Impedance measurement

[George Johnson]

All,
I could use your thoughts and experience with measuring RF impedances with 
"less than lab quality" commercial equipment.  I would like to measure and 
characterize things like antennas, baluns, ununs, etc over our typical HF 
range.  I have an old MFJ 259 but it lacks direct R and X measurement.  So 
I am looking at the MFJ 259B and Autek VA-1.  Both seem capable and my MFJ 
259 has been OK for antenna work I have done in the past.  I have had a 
good history with Autek products also.  Any pro and con experience would be 
appreciated.  Also, any other options would be useful.
Thanks,
George .. W1ZT
