NGP (No Ground Plane), 1/2 wave base loaded antenna. Molded high heat ABS mounting base features silver soldered connections, gold plated push pin contacts and O-ring. This is our most popular antenna, providing reliable performance in all types of conditions and applications. "No Ground Plane" means the antenna does not have to be attached to a metal surface (such as a vehicle roof or larger body panel). Although using a ground plane is always better, this NGP antenna performs great for all uses, drivers, teams, and applications. All antennas are already pre-tuned (cut) for application. Simply order, mount, and ride!
