[Elecraft] Antenna Analyzer (FA-VA4)

[Jim Brown]

Simple. Connect the analyzer output to one antenna, the input to the 
other.  Set the sweep range for that where you want to look at antenna 
coupling (usually one band for which the antennas are used). Make a 
sweep and tell the analyzer software to display S21 in dB.  S21 is the 
gain of a device or network.
