I think I see the problem. An ATU does not normally "autoadjust". You have to tell it that you want it to run.
You first set up the ATU with ant1 at whatever frequency you want to use. Then switch to ant2 and again set it up. Now both antennas are matched on that frequency. >From now on, you just switch between antennas and they are already matched and ready to go. The ATU remembers its settings for each antenna until you change them. If you switch to another band, you redo the matching, but when you switch back to the first band, the memory remembers the correct match for each antenna and resets itself accordingly. And if you jump back to the second band again, the ATU remembers the correct settings and is ready to go on that band. Great feature.
