What is the difference between 50 ohm and 75 ohm connectors?

The difference lies in the impedance, which directly impacts signal transmission.

50 ohm connectors are standard in most RF, wireless and data communications systems. They balance good power handling with acceptable loss, making them ideal for cellular networks, Wi-Fi, GPS and test instrumentation.

75 ohm connectors are designed for low-loss signal transmission, making them the preferred choice in broadcast, video and broadband systems where signal clarity is critical.

While some connectors physically intermate between 50 and 75 ohm versions, mixing impedances is not recommended. Doing so can create mismatches, increase reflections and degrade system performance.
