Wittenberg Antennen 103509 Adaptador coaxial BNC macho a SMA hembra, 50 ohmios, DC-4 GHz, latón niquelado

This Wittenberg Antennen 103509 adapter bridges BNC and SMA systems with a straight inline design, eliminating the need for custom cables when connecting test equipment or antenna feeds. Its 50 Ohm impedance matches most RF instrumentation, while the nickel-plated brass body and gold-plated center contact ensure stable signal transfer up to 4 GHz.

Highlights

• BNC male (plug) to SMA female (jack) configuration
• 50 Ohm impedance for RF and antenna applications
• Frequency range DC to 4 GHz
• VSWR ≤ 1.3:1 for minimal signal reflection
• Gold-plated center contact and PTFE insulator
• Durable nickel-plated brass housing

In daily use

Use this adapter to connect a BNC-terminated cable to an SMA device, such as a spectrum analyzer, antenna, or RF module. The compact straight body fits in tight spaces, and the secure threaded SMA side prevents accidental disconnection. With 500 mating cycles, it withstands frequent reconfiguration in labs and field kits.
