Here is the Federal Antenna Law that says Yes you can , Install , Use , Maintain , antennas above the roof and Yes you can install antennas in plain sight to get the best reception.
This a Federal Antenna Law because there people that despise and even hate antennas and never stop trying to make sure that know one has antennas.
Hoa's , housing covennuts , and etc. are well aware of this Federal Antenna Law yet still try to scam people into thinking no antennas.
This Law is in effect since the year 1996 , thats 16 years.
