An antenna module for a vehicle communication system can be attached to a vehicle using an attachment arrangement that includes a cast and a single module that incorporates a bolt with an integrated retainer clip. The attachment arrangement acts as its own snap. The retainer clip has a spring mechanism. The installer installs the attachment arrangement to a through hole, for example, in a vehicle roof panel. As the retainer clip passes through the through hole, it collapses around the body of the cast. After the retainer clip passes completely through the through hole, the spring mechanism causes the retainer clip to rebound back to its original span to temporarily hold the antenna module in place. The installer then tightens the bolt, thereby stroking the integrated retainer clip up the cast toward the vehicle roof panel. When the retainer clip contacts the vehicle roof panel, the installer further tightens the bolt to a recommended drive torque. This further tightening of the bolt creates a clamp load between the antenna module and the vehicle roof panel to provide a robust joint and watertight seal for the life of the vehicle.
