Telegärtner BNC Bulkhead Adapter Female to Female 50 Ohm Panel Mount, Nickel-Plated Brass, DC-4 GHz

In professional RF installations, passing a BNC connection through a panel or enclosure often requires a reliable, low-loss transition. This Telegärtner bulkhead adapter provides a secure female-to-female BNC interface, enabling clean cable routing through walls, chassis, or patch panels without signal degradation.

Who is it for

Network engineers, broadcast technicians, and RF installers who need to extend BNC connections through panels or create test points in 50-ohm systems. Ideal for video, instrumentation, and telecommunications applications up to 4 GHz.
