Choosing the Right Connector

Match your connector to your cable type: use annular connectors (e.g., UXP-4MT-12, UXP-NM-12) with rigid 1/2" hardline like LDF4-50A, and superflex connectors (e.g., UXP-4MT-12S, UXP-DM-12S) with flexible 1/2" coax. For carrier cell sites, always verify WPS compatibility with your connector series before ordering.
