[K3CAL] MFJ-259B Calibration

[N3AE]

Someone from the club asked me about an article I found on how to calibrate a MFJ-259B antenna impedance meter. Unfortunately, I forgot who asked me. Sorry to bother you if you're not interested. 


The procedure can be found at http://www.mfjenterprises.com/pdffiles/MFJ-259B_Calibration.pdf 


Also at http://www.w8ji.com/mfj-259b_calibration.htm 


The procedure requires some high accuracy loads constructed with 1% non-inductive resistors and PL-259 connectors. I bought the parts (connectors and 1% resistors) but have not put them together yet. 


Loads needed: 




A. Short 

B. 12.5- W load 

C. 50- W load 

D. 75- W load 

E. 100- W load 

F. 200- W load
