Just my .02:
1. - Why would you use "published" VFs? Use your analyzer to determine the true VF of your coax and then use that # when you are trying to make a jumper.
2. - There is no need to use a Tee and DL. The MFJ and RE instructions clearly state how to make a stub (jumper). Screw the coax pl-259 into the so-239 on the analyzer. For 1/4 wave stubs, leave the other end open. For 1/2 wave stubs, short the cut end. Tune for lowest X & SWR @ the desired Freq.
It is not that hard to short the coax for a 1/2 wave jumper, but the result is more accurate than using a tee and DL.
Where the "calibration" really comes in handy is when you take an antenna feedline, and re-calibrate your analyzer using it. Simply screw one end into the analyzer, and then go into the calibration mode. The calibration mode makes use of the open, shorted, and 50ohm loads which are screwed onto the other end of the feedline. Once calibrated, your feedline is now "transparent" to your analyzer.
Now you screw it into the antenna and you can tune your antenna with the analyzer through the feedline.
BTW, The newer 55s have Bluetooth so you can screw them into the bottom of the antenna and use you cell phone or tablet to see the tune.
