Antenna wont totally go down.

Hi, anyone with the antenna on rx 300 wont go down totally?

Most likely it is the retractable antenna mast.  It has a coiled nylon "tail" with teeth that allow it to be pushed up and retracted back.  I'm pretty sure some of the nylon teeth have broken off.  The following video will show you how to replace your mast.  It's actually a pretty simple job.  Just pay attention and take your time.  New mast is available at your friendly Lexus dealer Parts Department.  As repairs go, this one is pretty easy and not that expensive.  I did mine  a few years ago and this is the procedure I followed.

 

Good luck.

you can order the replacement on Amazon and get just the nylon part that breaks. Antennas get a little gummed up and it breaks the nylon teeth especially when old or cold,
