Verify Coaxial Continuity and Identify Four Drop Locations Simultaneously in One Fast Trip

The Klein Tools VDV5012101 Coax Explorer 2 is a portable coaxial cable tester and mapper engineered to evaluate circuit continuity on F-connector lines across four discrete structural endpoints. This pocket-sized device uses a single-button control panel to instantly identify pass, open, or short-circuit faults via an intuitive LED status display. Paired with four color-coded push-on remotes, this diagnostic tool maps complex residential and commercial satellite, security, and video distribution systems in a single production pass.

Best Used For:

  • Multi-Room Video Diagnostics: Mapping and tracing unidentified video coaxial runs throughout residential layouts or multi-family properties back to a splitter hub.
  • Continuity Fault Tracking: Scanning internal framing cavities to isolate open circuits or shielding shorts on damaged broadcast cables.
  • Satellite Drop Auditing: Labeling high-frequency infrastructure feeds across commercial offices and industrial telecommunication hubs.

Key Performance & Safety Features

  • Four-Port Mapping Array: Color-coded push-on remotes allow technicians to test and map four structural drops in a single walk.
  • Immediate LED Diagnostics: Diagnostic display instantly lights up clear diagnostic icons indicating a pass, open layout, or short circuit along the cable path.
  • Universal Line Support: Native internal electronics are fully compatible with standard RG59, RG6, RG6Q, RG7, and RG11 coaxial cable types.
  • Snap-On Component Carriage: Detachable structural holder clips the remote modules directly to the scanner body to eliminate accessory loss in the field.
  • Rapid One-Touch Cycles: Simplified single-button execution enables quick, repeated trace workflows across high-density connection setups.
  • Integrated Pocket Clip: Ergonomic frame design includes an integrated clip for fast pocket transport and immediate tool-belt accessibility.

What's Included

  • VDV512101 Coax Explorer 2 Tester
  • Removable Snap-on Remote Holder
  • 4 Color-Coded Push-on Remotes (Red, Blue, Green, Yellow)
  • Female-to-Female F-Adapter
  • Two AAA Alkaline Batteries
