[Elecraft] Antenna Analyzer (FA-VA4)

[Wes Stewart]

In this case think of the network analyzer as a transmitter with a receiver 
tuned to the same frequency.  Before testing you connect the two together and 
normalize the receiver response to unity at each test frequency. Now connect the 
transmitter port to one antenna and the receive port to the other antenna.  The 
response will be some fraction of unity, which can be presented as % 
transmitted, or more often in dB.
