My primary HF antenna is a trap 80/160 meter dipole.
It works good for those bands with no need for a tuner.

I'm shopping for a new HF rig, a TS-850SAT and I was
wondering how good the built in tuner would work with
the 80/160 antenna on higher bands, mainly 40/30/20m.

Anyone know?

It would probably tune, but it's not really meant to feed "all band"
antennas.
I wouldn't plan on that myself...Those tuners cost too much to abuse in
that
manner...They are really meant to be used as line flatteners. IE: give
you a
wider usable bandwidth with the solid state finals. Your load should be
in
the ballpark to begin with...IE under maybe 5:1 or so??? MK
