The ALFA ASP-NM-NM is a spring-style antenna adapter with N-Male connectors at both ends. The adapter’s mating thread is specially made longer to allow it to pass through the mount.

The spring adapter is designed for use on RVs/ trucks/ cars/ marines. The antenna adapter is extremely durable and reduces the vibrations, resistance and shocks that are inevitably encountered when driving, thus protecting the antenna from mechanical damage.
