Telegärtner BNC T-Adapter, BNC Plug to 2x BNC Jack, 50 Ohm, Nickel-Plated Brass, Gold-Plated Contacts J01005A0004

When a single BNC signal must feed two devices or two sources must be combined, a reliable T-adapter is essential. This Telegärtner BNC T-adapter splits one BNC connection into two, maintaining a constant 50 Ohm impedance for clean signal distribution in video, RF, and test environments.

Who is it for

System integrators, broadcast technicians, and RF engineers who need to split a BNC signal without introducing reflections or signal loss. Ideal for CCTV, instrumentation, and telecommunications where space is limited and performance is critical.
