Yes, but it also costs the HOA attorney fees to take you to court. When they send you a violation notice letter, send them (and their attorney) back a copy of the FCC rule and tell them that if they pursue the matter that you are going to counter-sue them for your attorney fees and harassment. They can't win because they can't overrule the federal government. HOAs seem to have "unlimited power" but they don't, they have to abide by the same regulations and laws as everyone else does. They get away with the things that they do because most people are afraid to fight them.
