[TowerTalk] Idea for the 259B ?

It has been wondered: 

Could  the next iteration of the MFJ-259 (maybe the
 MFJ-269 ?)  be designed to read the ACTUAL impedance
 at the antenna terminals, not just at the shack end of the
 feedline?  In other words, add a chip programmed to do the
 Smith chart calcs and display the result.  I bet it will be
 coming soon.

But maybe the actual feedline length would also have to be
known,  probably could not be a random unknown.  And the
259B  could not be used to determine the length,  as the line
would be terminated in who knows what Z,  hi.

Well,  it was a thought.
