[TowerTalk] Reactance at end of feedline

[Paul Christensen]

Pete,

Does your MFJ 259B separate out reactance and provide the sign (complex R+jX 
rather than only Z magnitude)?   I thought some MFJ models only read 
magnitude of the impedance.

If the 259B reads complex Z, did you observe a point where reactance went 
from one sign to the other as it crossed zero?  If we knew the feedpoint Z 
and type of line (we know the line length), we could then easily calculate 
the Z at the input end of the line, including sign of the reactance and 
compare it against your results.

Paul, W9AC
