Product Description
UHF-Female SO239 Cable Crimp Connector LMR600 Coaxial Cable
50-Ohm RF Connector | UHF Female / SO-239 | LMR-600 Cable | Heavy-Duty Construction
The ARS-G506-600 is a heavy-duty UHF-Female SO-239 cable-end connector designed specifically for terminating LMR-600 and other approximately 0.600-inch OD coaxial cables. This connector provides a secure mechanical and electrical termination for large-diameter, low-loss coaxial cable used in amateur radio, RF communications, antenna systems, and other high-power applications.
The SO-239 female connector features the standard 5/8"-24 UNEF mating thread for connection to UHF Male PL-259 plugs. Its robust brass construction and silver-plated finish provide excellent durability and reliable RF conductivity.

What Is a UHF-Female SO-239 Connector?
The SO-239 is the commonly used designation for the female member of the UHF connector family. It features an internally threaded receptacle that accepts the threaded portion of a standard PL-259 UHF Male connector.
Unlike constant-impedance RF connectors such as Type N, the UHF connector family was developed primarily for lower-frequency communications applications where robust mechanical construction and high-power capability are important.
LMR-600 Compatibility
The ARS-G506-600 is designed around the large diameter and construction of LMR-600 coaxial cable, which has an approximately 0.600-inch (15.2 mm) outer diameter.
It is suitable for applications where larger coaxial cable is selected for its low-loss characteristics, particularly on longer feedline runs.
Common Applications
Amateur (Ham) Radio
- HF and VHF base stations
- High-power transceiver installations
- Large coaxial feedlines
- Antenna tuners and switches

Antenna Systems
- Long-distance antenna feedlines
- Base-station antennas
- Antenna switching systems
- Lightning protection and grounding assemblies
Commercial & Communications Equipment
- RF communications systems
- Low-loss coaxial cable assemblies
- Test and measurement equipment
- Legacy UHF RF equipment
- High-power, lower-frequency RF systems

Installation
The ARS-G506-600 is intended to be installed on LMR-600 coaxial cable using the appropriate cable preparation and termination tools. The cable jacket and shielding should be stripped according to the recommended dimensions, with the center conductor properly positioned in the center contact.
A properly installed connector should provide firm mechanical retention of the cable shield and jacket while maintaining a reliable electrical connection through the center contact.
Always verify cable dimensions, stripping dimensions, tooling, and connector fit before production installation.
Important Notes
UHF connectors are non-constant-impedance RF connectors and are traditionally used for HF and lower-frequency VHF applications. While they can handle substantial RF power, connector performance at higher frequencies depends on the specific application, cable assembly, installation, and mating components.
For outdoor installations, the connector should be properly weatherproofed to protect the cable termination from moisture and environmental exposure.
