Summary
J-Plug test jacks are used in AM/MW tuning networks at points where convenient insertion of an impedance bridge or other test instrument may be desired. Kintronic Laboratories manufactures a J-Plug test jack for any application you may have. Plug-in meter handles are also available to allow the insertion of a thermocouple RF current meter into a test jack.
