HOA's have been aware of this Federal Law for a long time and keep there mouth shut about it so they can scam people in to thinking they can't put a antenna on the roof.
http://www.fcc.gov/mb/facts/otard.html. Think about it , antennas are made of aluminum and plastic , if some one dislikes or even hates aluminum and plastic what does that say about that person. Do people dislike or even hate the vent pipes that stick up out of the roof?? Do people dislike or even hate the air conditioning units that are on the roofs of houses?? And if so , Are these people crazy , and do crazy people run our lives?? HOA's are the low life scum of the universe.
