Picture 13: The Calculated LC Match Value on FAA-450
We could use the charts below to represent them. Each set of the values can transform the mismatched impedance to a true 50
OHM system.

Smith Chart:
FAA-450 also support the smith chart display. There is a green point mark in the circle (smith chart). The
diameter of the circle is labeled 10, 25, 50, 100, 200 ohms. Normally, for a well matched 50 ohm system, the green point mark
should be located rightly on the diameter line of the circle, without any up or down offset, and that says X = 0. For a detailed
information on how to use smith chart, please read the Smith Chart chapter of ARRL Antenna Book.

C. Other Information:
There is also a small area of screen that shows the SWR plot in the span of +-500KHz, from SWR1.0 to SWR 3.0. It is really
convenient for monitoring the band-width of an antenna as you do not need to go to the panoramic scan.
