## Summary description

DELOCK 91788 is a single RP-SMA coaxial connector designed for 50 Ω systems and compatible with RG-174 and RG-316 cables. The compact metal connector measures 8×18×8 mm and is supplied in a polybag. It provides a reliable mechanical and electrical connection for RF, antenna, and test applications where standard RP-SMA termination is required.

## Long description

DELOCK 91788 is a compact RP-SMA coaxial plug intended for 50 Ω radio frequency systems and compatible with RG-174 and RG-316 cables. The metal connector measures 8×18×8 mm and is supplied with a heat-shrink sleeve in a polybag. It is designed to provide a mechanically secure and electrically reliable termination for antenna connections, RF modules and test setups where RP-SMA male termination is required.
Advantages
The connector offers a standardized RP-SMA interface for straightforward mating with RP-SMA female sockets, ensuring correct polarity for applications that require reverse-polarity SMA. Its compact metal body and gold-coloured plating support consistent contact quality and basic corrosion resistance. The included shrink tube helps to provide strain relief and a neater cable transition after crimping.
Suitable for
 Connecting antennas to wireless routers, gateways or modems that use RP-SMA connectors
 Terminating RG-174 or RG-316 coaxial cables for RF modules and small form-factor assemblies
 Laboratory and test setups requiring a 50 Ω RP-SMA male interface
 Repairing or replacing damaged connectors on short coaxial pigtails
When it may not be suitable
This connector is intended for RG-174 and RG-316 cable diameters and is not suitable for larger-diameter coaxial cables or non-crimp installation methods. It is designed for 50 Ω systems; it is not appropriate for 75 Ω applications where impedance mismatch could affect performance. The connector is a single-piece plug and does not include a pre-assembled cable or adapter.
Key specifications
 Impedance: 50 Ω
 Compatible cable types: RG-174, RG-316
 Connector type: RP-SMA (reverse polarity SMA) male
 Material/finish: metal body with gold-colour plating
 Dimensions: 8 × 18 × 8 mm
 Package contents: 1 connector with heat-shrink sleeve
How to use
Prepare the RG-174 or RG-316 cable by stripping the outer jacket, braid and dielectric to the recommended lengths for crimp termination. Slide the crimp ferrule and heat-shrink sleeve onto the cable, insert the conductor and dielectric into the connector body, and crimp the ferrule according to the compatible crimp tool and ferrule dimensions. After crimping, position the heat-shrink sleeve over the joint and apply heat to shrink it for strain relief and improved insulation. Finally, verify the mechanical retention and continuity with a basic continuity or VSWR check if required.
What to consider before purchase
 Ensure the target device uses RP-SMA male or female polarity and that reverse-polarity RP-SMA is the required interface
 Confirm cable compatibility with RG-174 or RG-316 diameters and the crimp ferrule dimensions you will use
 Verify that a 50 Ω impedance matches your system to avoid signal reflections
 Check that you have the appropriate crimping tool and, if needed, a continuity or RF test instrument to validate the connection
Usage recommendations
For reliable RF performance, use the connector with RG-174 or RG-316 cable only, perform proper crimping with the recommended tool, and apply the supplied heat-shrink sleeve for strain relief. Inspect terminations visually and electrically before deployment to ensure low-loss connections.
