Southwest End Launch Connector Comparison: -6 & -12 Series

Southwest End Launch Connector Comparison: -6 & -12 Series

Posted by HASCO RF on 4th Aug 2026

Southwest Microwave’s -6 End Launch Connectors and ‑12 End Launch Connectors deliver the same industry‑leading high‑performance RF capability, with the ‑12 offering notable advantages for many designs.

The ‑12 provides this performance in a more cost‑efficient format, helping customers reduce overall system cost without sacrificing electrical performance or reliability.

Both connector styles use the same launch geometry because they share identical transition block dimensions. The key distinction is the mounting approach: the ‑12 is a thread‑in connector that installs directly into the transition block, while the ‑6 is a field‑replaceable 4‑hole flange connector secured to the block.

For applications that benefit from a thread‑in solution and where system cost is an important consideration, the ‑12 offers an excellent balance of integration simplicity, performance, and value.
