It ships as five pieces: the connector body, an end cap, a ferrule, a length of heat shrink, and an insulator — everything needed to complete one cable end in a single order line. The right-angle, free-hanging body routes the cable exit perpendicular to the mating axis, saving space in tight enclosures where a straight plug would force a bend radius that strains the braid. ## Why 75 Ohm Matters for This Connector The insertion loss is rated at 0.6 dB, a figure that holds across the SMB frequency band when terminated to the specified cable group. The centre contact is solder-terminated; the shield is crimped via the included ferrule. The heat shrink covers the crimp area for strain relief and environmental sealing. The kit is designed specifically for RG-179 double braid — the ferrule diameter and insulator length match the cable's dielectric and braid lay, so no adapter or substitute ferrule is needed. The free-hanging mount means the connector is not panel-mounted — it terminates the cable end and mates with a bulkhead jack or another in-line receptacle. The right-angle body keeps the cable running parallel to the mating face, which is useful when routing coax along a chassis wall or inside a swing-out rack.","metaTitle":"Amphenol 142176-75 SMB Plug, 75 Ohm, RG-179, Right Angle","metaDescription":"Amphenol 142176-75 SMB plug, 75 Ohm, for RG-179 double braid cable.

It is physically smaller, uses a snap-on rather than bayonet lock, and is impedance-matched to 75 Ohm cable like RG-179.
