Despite what your homeowner's association or governing authority in the USA tries to tell you, the FCC ruled over 15 years ago that homeowners associations and other governing authorities may not restrict the installation of antennas on the roof of your private residence for the purposes of TV, radio or internet reception. If that clause exists in your governing authority's regulations, or in a deed restriction, it is in error and is unenforceable. The burden of proof is placed on the governing authority, and they can be liable for damages if they try to enforce "no-antenna on the roof" rules. Please see the attached link to the FCC website where the details of the law are explained. I hope that you find it useful.
