ABSTRACT:
The present invention is directed to a multisize coaxial cable testing device having a housing, a transmitter-analyzer unit and a receiver unit. The transmitter-analyzer unit is located in the housing and includes an on/off switch, a power source, wiring, a circuit board with resistors to regulate current flow, and three or more different size three-wire coaxial cable connectors. The transmitter-analyzer unit also includes at least two signal lights and the power source is connected to each of the cable connectors through the circuit board and wiring. The signal lights are also connected to the wiring to signal the malfunction of a particular wire of a three-wire coaxial cable when tested. The receiver unit receives current from the transmitter-analyzer unit and returns current to the transmitter-analyzer unit. The receiver unit has three or more different size three-wire coaxial cable connectors of the size and type as the connectors of the transmitter-analyzer unit. These diodes and resistors via the wiring are connected to the three-wire cable connectors so as to complete a circuit for testing in conjunction with said transmitter-analyzer unit when the on/off switch is on and a plug at one end of a cable to be tested is connected to a connector of said transmitter unit and the plug at the opposite end of cable to be tested is connected to a connector of said receiver unit.
