The 172102H243HEX: This plug is built for Belden 9913, 9914, and LMR-400 — the three most common low-loss 50 Ohm cables in the 0.405-inch diameter class. The crimp-on shield termination and centre contact crimp give a repeatable, gas-tight connection that holds the impedance through the transition. The threaded coupling nut provides weatherproof sealing when mated to a standard N-type jack.
RF Performance and Duty
The 0.15 dB insertion loss at 11 GHz is low for a field-crimp N plug — the PTFE dielectric and precision-machined centre contact keep the signal path clean. The gold-plated centre contact and 500-cycle rating mean this connector can handle repeated mate-demate in test or field-service setups without wiping the plating.
