SSB 7401 N Male Plug for Ecoflex 10 / Aircom Premium / RG213 / LMR400

The SSB-Electronic 7401 is a high-quality N male plug, designed for installation on 50Ω coaxial cables such as Ecoflex 10, Aircom Premium, RG213 and LMR400.

This connector is suitable for radio frequency applications where a robust, reliable connection with good electrical performance is required. The connector uses a soldered inner conductor and screw/clamp outer conductor system, providing a secure assembly when installed according to the manufacturer’s technical instructions.

With 50Ω impedance, operating frequency up to 10GHz and working voltage up to 1000V RMS, this plug is suitable for antenna installations, low-loss coaxial cables, amateur radio equipment, VHF/UHF/SHF systems, reception, transmission and RF instrumentation.

Its construction includes a PTFE insulator, nickel-plated brass body, gold-plated brass pin, rubber/silicone gaskets and an operating temperature range from -55°C to +155°C, making it suitable for demanding installations and RF environments.

Correct assembly requires proper cable preparation, soldering of the centre pin and tightening with suitable spanners. For Ecoflex 10 and Aircom Premium, the mounting instruction specifies different pin diameters, so the correct pin must be selected according to the cable used.

Important note

Before assembly, always confirm the coaxial cable compatibility, inner conductor diameter, pin type, cable preparation, impedance, operating frequency, applied power and installation conditions.

Correct assembly is essential to ensure good RF performance. The inner conductor must be carefully soldered and the connector body must be tightened according to the manufacturer’s instruction. For Aircom Premium, the 2.8mm hole pin is indicated, and for Ecoflex 10, the 3.0mm hole pin is indicated. For other compatible cables, such as RG213 or LMR400, always confirm the suitable pin before assembly.

After installation, it is recommended to check continuity, absence of short circuit, mechanical tightness and system SWR before transmitting. Coaxial cable, antenna and assembly tools are not included unless expressly stated otherwise.
