To disconnect, remove the foam anti-vibratilon tape from the connectors (grasp both ends of the connectors and twist while pulling connectors apart).

2. Using a high quality Digital Volt Ohm Meter, measure the resistance of the cable center conductor to the threaded portion of the base where the antenna mast is attached.

3. Measure the resistance of the outside conductor of the cable to the antenna base mounting nut.

4. A resistance reading higher than 0.2 ohm in step 2 or 3 indicates the need to replace the antenna base and cable assembly, P/N 56006789.
