Matt, what firmware do you have in your ts-480-s?
The last upgrade, I think it was version 1.04, extended the tuning range of
the internal tuner.
Here mine tunes anything under 6/1.
Yes the external automatic tuners will do more, but if you can do it
internally, save the money.

Subject: Question about Auto Antenna Tuners

Hi, Folks.  I have a TS480SAT which has a built-in auto tuner.  Had one of
my ham buddies come over and test the setup he and his buddies put up, an
UltraLight Junior dipole strung between two trees and my house.  We noticed
that on 3.550MHZ, we were getting 4-1 SWr, egen though the antenna can go
down that far - 80-10 meters.  Above 3.8MHZ, the antenna tunes up.

My question is:  if I buy an external auto tuner, will I have more
flexibility in getting a match.  Are the the built-in tuners mor limited
than the external ones?  And what accessible tuner would you recommend if
there is a difference?Thanks in advance.--Matt, N1IBB.
