the best way is to first ohm it with the antenna disconnected test from center to shield for "open" it should be open then test from center to center for "short" it should be shorted
replace the antenna and test the VSWR on your antenna
To replace the antenna on a 1974 Mercedes Benz 450SL, first, remove the interior panel or trim covering the antenna base to gain access. Disconnect the old antenna by unscrewing it and detaching the electrical connector. Install the new antenna by reversing the steps: secure it in place, reconnect the electrical connector, and replace the interior panel. Finally, test the antenna to ensure it functions properly.
To replace the antenna on a 1987 Grand National, begin by removing the interior panel or cover that conceals the antenna base, typically located near the rear passenger side. Disconnect the electrical connector and unscrew the antenna mast from the base. Install the new antenna by reversing the process: screw the new mast onto the base and reconnect the electrical connector before replacing the interior panel. Finally, test the antenna to ensure proper functionality.
To replace the power antenna shaft on a 2001 Firebird, first, remove the interior trim panel around the antenna to access the assembly. Disconnect the power connector and unscrew the antenna from its mounting point. Then, pull the broken shaft out and insert the new one, ensuring it is properly aligned. Reassemble the antenna, reconnect the power, and test it to ensure proper operation.
Remove the old antenna. Attach the universal antenna to the radio and replace the radio after finishing the task. Install the new antenna. Test to ensure the wiring works.
The code reader test connector, on your Ford E2 50, is located beneath the dashboard on the drivers side. The connector is on the left side of the steering column.
If you run the antenna under test in the receiving mode, then while it is rotated, you'll monitor signals received by the antenna under test. If you run the antenna under test in the transmit mode, then while you rotate it, you'll monitor signals received by a different antenna on the test range. Either way, the varying signal must be monitored at the receiving end of the link. It's a lot more convenient, and a simpler configuration, to have the signal monitor and the rotation/excitation controls for the antenna under test in the same place, in order to react appropriately to any funny things noted during the test run.
The tool designed specifically to test DC current from a Molex connector is called a Power Supply Tester.
A quiet zone in antenna measurement refers to an area surrounding the antenna test zone where electromagnetic interference is minimized to ensure accurate testing. It is essential for obtaining precise measurements of the antenna's radiation pattern and performance. The quiet zone is achieved by reducing reflections, scattering, and diffraction from surrounding objects and walls through proper test setup and shielding.
To replace the antenna on a 1956 Thunderbird, first, remove the existing antenna by unscrewing any retaining nuts or screws from the base. Then, disconnect any wiring associated with the antenna. Install the new antenna by securing it in place with the retaining hardware and reconnecting any wires. Finally, test the antenna to ensure proper functionality.
To replace the antenna on a 1986 C10, first, remove the old antenna by unscrewing it from the base, which is typically located on the fender or the roof. Disconnect any wiring connected to the antenna, then install the new antenna by reversing the process: connect the wiring, secure the antenna to the base, and ensure it's tight. Finally, test the radio reception to confirm the new antenna is functioning properly.
To replace the antenna on a Volvo 850, first, remove the plastic cover inside the trunk area that conceals the antenna base. Disconnect the antenna cable and unscrew the antenna from its mount. Install the new antenna by screwing it into place, reconnecting the cable, and replacing the plastic cover. Finally, test the radio to ensure proper functionality.
There should be an " EEC TEST " connection in your engine compartment near the battery ( or power distribution box if you have one )
