Boxwave 2PCS Coaxial F Female to RJ45 Male Audio Adapter

Two-piece coaxial-to-RJ45 adapter set

This pair of adapters converts an F-type female coaxial connection into an RJ45 male plug for use with cable testers and line tracers. They enable a network-port instrument to access BNC-style monitoring, video or cable-TV lines. Each unit combines plastic and metal construction for light weight and resistance to breakage. The package supplies two identical converters for paired testing.

Replaces makeshift BNC-to-RJ45 wiring

Technicians who previously built custom leads or used loose couplers can now plug a standard network-interface tester directly into coaxial infrastructure. The jump is worth it when a cable finder or continuity checker lacks a native BNC port but must trace surveillance, CCTV or CATV runs. Because the adapters must be used in pairs, a single unit cannot complete a test on its own.

Limited to line-tracing and continuity functions

The product is explicitly not suitable for router, Wi-Fi or data-network configurations. It passes only the physical signals required for cable identification and fault location, not Ethernet traffic or broadband modulation. Users must connect both ends of a coaxial run with matching adapters to obtain a valid result.
