DELTA BNC-stekker naar BNC-stekker rechte koppeladapter, 75 Ohm, vernikkeld messing, PTFE-isolator

For installations where two BNC cables must be joined without signal loss or bulky barrels, this DELTA BNC-W/BNC-W coupler delivers a direct, in-line connection that preserves impedance and keeps your video or RF chain tidy. Unlike generic adapters that rely on plastic bodies and loose centre contacts, this model uses a machined brass housing with nickel plating and a PTFE insulator to maintain a stable 75-ohm path from DC to 4 GHz.

Highlights

• BNC male to BNC male straight coupler for joining two BNC female cables or devices
• True 75-ohm impedance, ideal for CCTV, broadcast video, and RF test setups
• Nickel-plated brass body and contacts resist corrosion and wear over 500 mating cycles
• PTFE insulator ensures low loss and consistent performance up to 4 GHz
• Compact, tool-free installation — simply screw the BNC connectors onto each end

In daily use

This coupler is the missing link when a cable run is just a bit short or when you need to extend a patch panel connection. Because both ends are BNC male, it works directly with standard BNC female sockets found on cameras, monitors, and test instruments. The straight-through design adds minimal insertion loss, and the nickel-plated surfaces provide a secure grip without galling. In CCTV systems, it allows you to join pre-terminated cables without re-crimping, saving time on site. For RF benches, it offers a reliable way to extend measurement cables while keeping VSWR below 1.2:1 at 3 GHz.
