you need 10 mechanical points and then go to the penthouse and they will be there
------
WRONG answer. you need more than 5 mechanical points and yes, they're in the penthouse but you gotta wait for 6 pm to 10 pm and the robot Alfred will go recharge battery. when he's gone you go steal blueprints.
PS 6 pm in Sims time. as you know the Sims time is about one hour slow.
WRONG!, you need 5 mechanical points then steal the blueprints while the robot goes and charges his batteries at 6 pm 10 pm (if you need to change the time on your DS to 6 pm or 10 pm or in between.
Wrong, sims time is the same time that u put on your ds so u must have the wrong ds time

Once you get 5 mechanical skill points you have to complete the mission "Earn Mechanical 5, break into the Penthouse, and steal the Blueprints" and when you obtain the blueprints for the antenna you have to take it to the alien emperor: Emperor Zizzle.
You DO NOT need 5 mechanical skillsAll you have to do is:Go to the Penthouse between 6 to 10 pmOptimum Alfred is not there
Technically you can't However, if your sim is a kleptomaniac, he/she can visit a house at night, steal from outside or ask to be invited in, and steal from a room with no sims in it.
you have to have the trait 'kleptomaniac', then you go out somewhere, click on something and then you will get the option to steal it
