My ATSA antenna only goes up  when I try to tune the antenna   it well go down or up with the up or down button

How do I reset the  antenna, or do I need to send it back to  Yeasu?

The ATAS antenna is very sensitive to common mode current. Make sure it is well and truly grounded properly first.

That isn't all. If you don't choke off the common mode (as mentioned in the owner's manual), you'll have more issues than not tuning down!

As Conor alluded to, mounting is everything. Unfortunately, most folks mount their ATAS using a K400 or similar clip on mount. No matter how careful you are, sooner or later the set screws will loosen, and the common mode with go through the roof. Sanding to bare metal isn't the answer either, as this does nothing but promote rust which exacerbates the ground issue in the first place.

OK I found out what was going on with the ATAS-120  it lost its memory,and I had to reset it by tuning on one band,then going to anther band and tuning it 

I'm now a happy camper,and once again can go "hello audio mobile"
