An antenna module for use a non-conductive cab of a motor vehicle includes a dielectric substrate and one or more antenna loops arranged on the substrate. The substrate is adapted to be installed between the headliner of a cab and the dielectric roof. The module may include a CB antenna loop, an AM/FM antenna loop, a cellular mobile telephone antenna loop, and a global positioning system antenna, without the need for any antenna structure external to the cab. The antennae are arranged on the module in a nested configuration. A CB antenna, provided with loading coils, forms an outer loop. An AM/FM antenna loop, including a capacitor yielding a substantially short circuit connection in the FM frequency range, forms a FM frequency antenna loop and an AM frequency dipole, within the CB loop. A multiloop array cellular telephone antenna is arranged within the AM/FM loop. A standard crossed dipole GPS antenna is positioned in an area between the CB loop and the AM/FM loop near one corner of the substrate. Coaxial antenna feedlines connected to the various antennae are routed through cab support posts to associated electronic circuitry in the cab.
