US Patent 9024829 Hidden CB antenna arrangement

A CB antenna arrangement for use in a raised roof of a truck cab enables the CB antenna to be hidden from view while maintaining good performance. An LC circuit is mounted in the space between the headliner and the raised dielectric roof and is connected to one of the metallic pillars of the truck cab. A CB antenna is connected to the LC circuit, and is mounted to and extends along the inside surface parallel to the driver's side or the passenger's side. The LC circuit is configured to block signals outside the CB frequency range, and the metallic pillar provides a ground plane for the CB antenna.
