Product Description
QMA Male Plug to Mini-UHF Female RF Coaxial Connector Adapter
50-Ohm QMA Male to Mini-UHF Female RF Coaxial Adapter
The American Radio Supply ARS-G695 is a compact RF coaxial adapter designed to connect equipment using a QMA male plug interface to equipment or cables using a Mini-UHF female jack. This adapter provides a convenient transition between the quick-connect QMA interface and the threaded Mini-UHF connection commonly found on radio communication equipment.
The QMA interface provides a quick-connect, snap-on mating system, making it useful in installations where rapid connection and limited space are important. The Mini-UHF side provides a traditional threaded connection for compatible coaxial cables and radio equipment.

Applications
The ARS-G695 is well suited for RF interconnection applications where a QMA interface must be adapted to Mini-UHF.
Mobile & Emergency Communications
Useful with multi-band mobile and public-safety radio systems where QMA-equipped equipment must interface with existing Mini-UHF antenna cables or accessories.
Automotive & Fleet Communications
The compact form factor and quick-connect QMA interface can be advantageous in vehicle installations where installation space is limited and rapid RF connections are desirable.
Amateur Radio & Wireless Communications
Suitable for RF systems requiring a transition between QMA and Mini-UHF connector interfaces.
RF & Antenna Systems
Useful for adapting compatible coaxial cables, antennas, radio equipment, and RF accessories while maintaining a 50-ohm connection.
Mechanical Configuration
QMA Male → Mini-UHF Female
The QMA male side incorporates the center contact and snap-on locking mechanism associated with QMA connectors. The Mini-UHF female side provides the threaded socket required for mating with a compatible Mini-UHF male connector.
Important Note
Actual maximum frequency performance, plating, and electrical characteristics can vary depending on the specific manufacturing configuration and mating components. The 3 GHz frequency specification should be treated as the typical application range unless a controlled test specification for the specific production version establishes a different rating.
