Rf Industries RFU-621 Straight Adaptor from Mini UHF Male to UHF Female

The RF Industries RFU-621 is a straight RF coaxial adapter that converts a Mini UHF male interface to a UHF female SO-239 interface, enabling seamless integration between equipment and cables that use these two common connector standards. Built with a nickel-plated body, gold-plated contact pin, and PTFE dielectric insulation, the RFU-621 delivers reliable electrical performance and signal integrity at a 50-ohm impedance matched to standard RF coaxial systems. Its compact, straight-configuration form factor makes it well suited for use in two-way radio, amateur radio, and broader RF communication installations where interface conversion is required without introducing unnecessary bulk or cable routing complexity.

Key features & benefits

• Mini UHF Male to UHF Female SO-239 Conversion — Provides a direct, straight-configuration interface bridge between Mini UHF male connectors and UHF female SO-239 ports, eliminating the need for adapter cables in space-constrained installations.
• 50-Ohm Impedance Matched — Designed to the 50-ohm impedance standard common to RF coaxial systems, helping to maintain consistent signal transmission and minimize reflections at the connector junction.
• Nickel-Plated Body Construction — The nickel-plated outer body provides corrosion resistance and durable mechanical protection suited for repeated connection cycles in professional RF environments.
• Gold-Plated Contact Pin — Gold plating on the contact pin promotes low-resistance electrical continuity and long-term connection reliability, resisting oxidation over the service life of the adapter.
• PTFE Dielectric Insulation — Polytetrafluoroethylene dielectric material offers excellent electrical insulating properties and thermal stability, contributing to consistent RF performance across operating conditions.
• Compact Form Factor — At 1.3 in wide and 0.8 in in both depth and height, and weighing only 0.32 oz, the RFU-621 adds minimal size and mass to any RF assembly or panel connection.
