Per Rob Long, the antennas do not autostow when commands cease. We have 
to manually park/stow the antennas.

Cheers,

You have to find something that you love enough to be able to take 
risks, jump over the hurdles and break though the brick walls that are 
always going to be placed in front of you. If you don't have that kind 
of feeling for what it is you are doing, you'll stop at the first giant 
hurdle.
