Wentronic Goobay RP-SMA puristusliitin RG-174 ja RG-316 (51696)

RF technicians and antenna installers working with thin coaxial cables like RG-174 or RG-316 will find this RP-SMA crimp jack a reliable choice for terminating cable ends. It is a reverse-polarity SMA female connector with a crimp attachment for the shield and solder for the center conductor. The connector is straight in style and built with a brass body plated in nickel, a gold-plated center contact, and a PTFE dielectric. It supports a 50 Ohm impedance and operates from DC to 6 GHz, making it suitable for WLAN, antenna, and general wireless communication links.

Key specifications

• Connector type: RP-SMA (Reverse Polarity SMA)
• Gender: Female (Jack)
• Mounting: Crimp (shield), solder (center conductor)
• Compatible cable: RG-174, RG-316
• Impedance: 50 Ohm

Why choose it

The RP-SMA interface prevents accidental mating with standard SMA connectors, which is essential in systems where reverse polarity is specified. The crimp termination provides a secure mechanical bond for the cable shield, while the gold-plated center contact ensures low contact resistance and corrosion resistance. The PTFE dielectric maintains stable electrical performance across a wide temperature range.

Ideal use cases

• Terminating RG-174 or RG-316 cables for Wi-Fi antennas and access points
• Building custom RF patch cables for wireless equipment
• Repairing or replacing RP-SMA connectors on antenna leads
• Prototyping RF circuits in labs and workshops

Good to know

This connector is a component, not a complete cable assembly. It requires a crimp tool sized for the cable and soldering of the center pin. The nickel-plated brass body offers good durability and conductivity, and the operating temperature range covers harsh environments from extreme cold to high heat.
