Honestly, I learned the the antenna extended by accident.
When I purchased my Gyration, it worked perfectly out to the box and both the keyboard and mouse worked a good 25 feet without the antenna extended. It wasnt until a couple weeks later that I moved the antenna a bit and it extracted out. LOL.
BTW -- my Gyration RF receiver quit working altogather a couple weeks ago and Gyration is sending me another RF receiver.
