Question

Which purpose BNC connector with 75 Ohms is used​

Answer 1

Answer:

75 ohm BNC connectors are primarily used in Video (particularly HD video signals) and DS3 Telco central office applications. Many VHF receivers use 75 ohm antenna inputs, so they often used 75 ohm BNC connectors. The 50 ohm connectors are typically specified for use at frequencies up to 4 GHz.
