The HDTVi or a better antenna can be put on a Patio.
Is there a Patio that is part of the east side of your apartment??
Or an area that one could call a Patio or etc. ??
Here is the Federal Antenna Law that says Yes you can , install , use , maintain , a antenna on a patio , or a area , that is part of your exclusive use and control.

The best way to get the signal from the antenna on the patio to the Tv in the apartment is to have a coax from the antenna go through a hole through the wall and to the Tv.
And before you say that you are not allowed to have a coax go through the wall.
Are there any of the small satellite dishes out side of the apartment building??
And how do the small dishes get the signal from the small dish to the receiver inside the apartment??
Is it coaxes through the wall??
The preferd way to get the signal from point A to point B is coax through the wall.
Here is another way to do it.
A flat coax.
