RP-TNC Jack for RG-8X and LMR-240 — What This Connector Does
The cable group covers RG-8X, Belden 9258, and LMR-240 — three common 50 Ohm cables in the 0.240-inch diameter class. If you are terminating one of these cables, the 122409RP is a direct fit. The shield is crimped, the centre contact is soldered, and the threaded coupling nut provides the mechanical retention.
What the 11 GHz and 50 Ohm Ratings Mean for Your RF Path
The 11 GHz maximum frequency means this connector will pass signals up into the X-band without excessive loss; the specified insertion loss is 0.18 dB, which is the loss through the connector itself at its rated frequency. For a field-installed jumper or antenna feed, that is negligible. If this connector lives on a test cable that gets mated daily, 500 cycles gives you years of service before the contact wear becomes a concern.
Cable Prep and Termination — What Ships in the Kit
The connector is free-hanging (in-line), so no panel cut-out is needed — it terminates the cable end and mates to a bulkhead or adapter via the threaded coupling nut.
