Here is a antenna that looks like a small satellite dish on Purpose.
It is not a satellite dish , it is in fact a Tv antenna.
Many apartment buildings have small satellite dishes out side of the buildings.
This Tv antenna will blend right in.
For your reception situation the antenna is mounted Up High in a manner that the roof does not block reception , and the antenna is aimed at about 25 degrees magnetic compass.
