Mast Antenna System
WARNING: This page is about a different car, the 2002 Pontiac Montana, 2002 Oldsmobile Silhouette, and 2002 Chevrolet Venture. However, it is still accessible from the selected car via links, so may be relevant.
- Measure the resistance from the coax center conductor to antenna mast. (Ohmmeter probes at points 2 and 7)
- Total resistance of center conductor from end to end (Ohmmeter probes at points 2 and 5):
- RG-58/RG-59 type cable-less than 0.20 ohms
- RG-62/RG-62M type cable-less than 3.5 ohms
- When checking the resistance, cautiously wiggle the lead-in tip and cable. Refer to TESTING FOR INTERMITTENT AND POOR CONNECTIONS .
- Replace the antenna and/or lead-in cable when the above readings are not obtained. Refer to Antenna Cable Replacement for service procedure.
