The petition was filed by the Satellite Broadcasting and Communications Association of America, Inc. (SBCA), Antenna Star Satellites, Inc., and Johnson TV & Satellite. The ordinance in question includes a requirement that antenna users obtain a $10 permit for installation of a satellite antenna, provide documentation of an antenna manufacturer's installation procedures, and remove an existing antenna when it is replaced by another. The requirement that any professional antenna installer have a valid construction business license is also being challenged. Comments are due Nov. 24 with replies due Dec. 11, 2009.
