Product Description
UHF-Female SO-239 to F-Type Female Coaxial Adapter
The RFA-8171 is a compact, high-quality coaxial adapter designed to connect equipment featuring a standard UHF female (SO-239) jack to coaxial cable assemblies using an F-type threaded female connection. This adapter provides a convenient way to interface radio equipment with commonly available television, broadband, and video coaxial cabling.
Constructed with a nickel-plated brass alloy body and gold-plated beryllium copper alloy contacts, the RFA-8171 provides excellent mechanical durability, corrosion resistance, and reliable electrical contact.

Applications
Radio Scanners & Receivers
Connects RG-6, RG-59, and other coaxial cables fitted with F-type connectors to scanners, receivers, and radio equipment equipped with an SO-239 antenna connection.
CB & Amateur Radio
Useful for adapting readily available household coaxial cable for basic receiving antennas, experimental setups, and radio projects.
Test Bench & Temporary Connections
Provides a convenient solution when testing or interconnecting equipment using different coaxial connector standards.
Important Impedance Note
The RFA-8171 bridges 50-ohm radio equipment and 75-ohm television/video coaxial systems. While this is suitable for many receiving and general-purpose applications, the impedance mismatch can produce some signal reflection and increased VSWR at higher frequencies. For critical RF transmission applications, use a properly matched 50-ohm connection.
Product Summary
The RFA-8171 SO-239 UHF-Female to F-Type Female Coaxial Adapter is a practical solution for connecting UHF-equipped radio hardware to readily available F-type coaxial cable. Its nickel-plated brass construction and gold-plated beryllium copper contacts provide a durable, reliable connection for radio, scanner, antenna, testing, and general RF applications.
