Connector Material Quality
Look for connectors with gold-plated contacts to ensure a reliable connection and prevent oxidation over time. Standard metal or plastic connectors may corrode and cause signal issues.
Gold plating is essential for long-term signal stability.
Cable Length Requirements
Measure the distance between your wall jack and your devices to determine the required cable length. Most splitters include a 3 to 5-inch cable which may limit placement options.
Ensure the cable length fits your workspace layout comfortably.
