Rf Industries RFU-501 UHF Male Connector PL-259 Coaxial Cables Silver PTFE

The RF Industries RFU-501 is a UHF Male (PL-259) coaxial connector engineered for reliable, low-loss termination on large-diameter coaxial cables commonly used in professional RF, communications, and broadcast infrastructure. Assembled via thread attachment, it is built with silver-plated body, shell, and contacts for excellent conductivity and corrosion resistance, while PTFE dielectric insulation delivers stable electrical performance across demanding service environments. The RFU-501 is a practical, field-proven choice for system integrators, installers, and technicians who require consistent, repeatable coaxial terminations on standard 50-ohm trunk and feeder cables.

Key features & benefits

• UHF Male (PL-259) Interface — Provides a standard PL-259 male interface, the widely adopted UHF connector format used across commercial, amateur, and professional RF installations for straightforward mating with SO-239 receptacles.
• Thread Assembly — Utilizes a threaded attachment method that ensures a secure, vibration-resistant mechanical and electrical connection, reducing the risk of intermittent contact in installed systems.
• Silver-Plated Body, Shell, and Contacts — All conductive surfaces — body, shell, and center contact — feature silver plating, delivering low contact resistance and strong RF signal integrity while resisting oxidation over the connector's service life.
• PTFE Dielectric Insulation — Polytetrafluoroethylene (PTFE) is used as the dielectric material, offering superior electrical stability, low signal loss, and resistance to moisture and temperature extremes compared to standard plastics.
• Broad Cable Compatibility — Designed to terminate a wide range of commonly specified large-diameter 50-ohm coaxial cables including RG-8/U, RG-213/U, RG-214, Belden 9913, CTN-400, LMR-400, and others, making it highly versatile for multi-cable environments.
• Adapter-Ready for Smaller Cables — When used with the separately available RFU-530 reducer, the RFU-501 can also accommodate RG-58/U and RG-142 cables; with the RFU-531 adapter it supports RG-8/X and RG-59/U, extending the connector's utility across a broader cable inventory.
