[TenTec] antenna analyzer reading?

If you read "Reflections" by Walter Maxwell; the function of the tuner 
at the rig is to adjust the matching to the line to account for the 
situation on the antenna end as well; well enough to minimize losses to 
the practical extent.  The whole of the tuner, transmission line, and 
antenna acts as a tuned system where the matching box adjusts such that 
the transmitter sees on 50 ohms non reacative, if the matching box has 
the proper range of adjustments for the band in use.  It is true that 
SWR extremes do not introduce as high a loss in parallel line as coax, 
for coax is a high current line, and parallel line is higher impedance, 
lower current.  Thus, I squared R losses are less than coax I squared I 
losses.
