RP SMA Male Connector Crimp for RG58 U LMR195 RG142 RG400 CABLE

This RP-SMA male crimp connector is a reverse-polarity RF coaxial connector designed for crimp termination on common 50 Ω coaxial cables like RG58 U, LMR195, RG142 and RG400. It enables reliable RF connections to devices, antennas, wireless modules and other RF equipment that use the RP-SMA interface standard.

Key Features:
✔ Type: RP-SMA male — reverse polarity connector for RF coax cable;
✔ Attachment: Crimp termination — secure mechanical and electrical connection with crimping tools;
✔ Compatible Cables: RG58 U, LMR195, RG142, RG400 (or similar);
✔ Impedance: 50 Ω — RF standard for antennas and wireless transmissions;
✔ Applications: ideal for antennas, Wi-Fi routers, radio modules, GPS and other RF systems.

What It Is:
The RP-SMA (Reverse Polarity SMA) connector differs from standard SMA by swapping the internal pin configuration — the RP-SMA male has internal threading and a receptacle rather than a protruding pin, ensuring compatibility only with RP-SMA counterparts. This is a common practice in wireless and RF equipment to meet regulation and prevent unintended antenna changes.

Installation:
Proper installation requires crimp tools and dies to compress the connector ferrule onto the cable’s outer braid, and often soldering the centre conductor to the connector pin for superior electrical contact. A well-crimped RP-SMA ensures low signal loss and robust mechanical performance.

Common Uses:
✔ Connecting antennas to Wi-Fi access points and RF modules;
✔ Radio communication systems including VHF/UHF and IoT modules;
✔ GPS/GNSS antenna connections;
✔ RF DIY and custom cable assemblies.

Benefits:

• Works with multiple types of coax cables for flexible integration.

• Reverse polarity compliance with RP-SMA RF devices.

• Provides stable low-loss RF signal transmission.

• Compact and durable construction for professional installations.
