Matt, yes the external tuners will match a much wider range than the 
internal tuners.  I use a Palstar AT 2000 that does a good job.  There are 
other brands that do a good job also and some cheaper I think. By the way, 
if you get an external tuner be sure to turn your internal tuner off because 
they don't work well when both on.   G L.

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.
