Tom,

since you have an internal tuner in your TS480, it will either tune the 
antenna or you'll get a SWR cw error message.  Just remember that an 
internal tuner is not very efficient, it usually sucks out between 10% 
and15% of the output power.  As Buddy mentioned, its not a good idea to hook 
up a watt or SWR meter after an internal tuner as your readings will be way 
off.

    Tom,

You do realize that the TW1 won't actually tell you anything about what =
your internal tuner is doing, right?

I mean, the meter goes before the tuner, which is impossible if the =
tuner is internal. So, yeah, you'll get your power out racing, but you =
won't get an active WR reading, at least not as far as your rig is =
concerned. It's going to see whatever the internal tuner matches to, but =
the TW1 won't, since it's necessarily in line after the tuner, not =
before.=20
