As you already know about here is the Federal Law that says Yes you can install and use a outdoor roof top tv antenna of any type or size.
http://www.fcc.gov/mb/facts/otard.html. . Think about this , antennas are made of Aluminum and Plastic , does a reasonable and clear thinking person frown up on Aluminum and Plastic. Is it Ok to dislike Aluminum And Plastic and push the dislike off on to others. Do these same people that dislike aluminum and plastic also dislike the aluminum and plastic that is part of the airconditioner that is on Their roof?? Do they dislike the metal and plastic sewer vent pipes that stick up out of their roofs?? Or do they vent the sewer smell in to their attic so that no vent pipes stick up out of the roof. Or is the Real Truth that they are unhappy and maladjusted humans that have found a way , antennas , to stick too other humans.
