SWR 350751 3-1/8″ Unflanged Coupler

The SWR 350751 is a precision-engineered 3-1/8″ Unflanged Coupler designed to provide a highly secure, ultra-low-loss splice between two un-terminated 3-1/8″ rigid transmission lines. Developed to give broadcast professionals a complete and rapid field-connection solution, this product brings outstanding structural integrity and electrical efficiency without the need for brazing or factory-flanged ends. It maintains a precise 50-ohm impedance, ensuring minimal VSWR across demanding high-power FM, TV, and telecom applications.

What makes this product exceptionally practical is its comprehensive, all-in-one configuration for field installations. The SWR 350751 comes fully equipped with two (2) heavy-duty 3-1/8″ line clamps for maximum mechanical grip, alongside a precision inline inner connector and a premium PTFE inline insulator (0526). This ensures a flawless, mechanically secure, and perfectly center-aligned electrical connection right out of the box, making it an indispensable component for custom transmission line routing, emergency repairs, and joining field-cut massive rigid coaxial sections.
