RP-SMA Male Crimp Connector for H155 Coaxial Cable

For RF installations where standard SMA polarity would cause a mismatch, this RP-SMA male crimp connector for H155 coaxial cable delivers the reverse-polarity interface required by many Wi-Fi access points, routers, and antenna systems. Unlike generic connectors that rely on adapters, it terminates directly onto H155 cable, preserving a clean 50-ohm path with minimal signal loss.

Highlights

• Reverse polarity SMA male (plug) configuration, ideal for Wi-Fi and WLAN equipment
• Precision crimp termination for H155 coaxial cable with solder center pin
• 50-ohm impedance, DC to 6 GHz frequency range
• Low VSWR (< 1.3:1 @ 6 GHz) and insertion loss (< 0.2 dB @ 6 GHz)
• Durable brass body with nickel plating and gold-plated center contact
• PTFE dielectric for stable performance across -40°C to +85°C
• Rated for 500 mating cycles

In daily use

Installers appreciate the straightforward crimp-and-solder assembly: strip the H155 cable, crimp the ferrule for strain relief, and solder the center pin. The straight body style fits standard bulkhead or panel cutouts, and the nickel-plated brass withstands repeated handling. Whether you are building a custom antenna lead or repairing an access point pigtail, this connector maintains a secure, low-loss connection.
