An antenna sniffer can be used along with the vehicles radio to locate hot spots that may be generating radio noise interference.
The antenna sniffer can be made from a old antenna lead in cable by cutting off the antenna base lead in. Then strip off approximately 6 cm (2 in) (3) of the outer coax shield (black insulation and braided wire) leaving the inner white insulator (1) and the center conductor wire (2). Use the longest antenna lead in as possible (4), for best results.
Important: When using the antenna sniffer keep your hand away from the stripped end while searching for noise.
By plugging the antenna sniffer into the radio antenna socket you can use the stripped end to search for hot spots.
To use the antenna noise sniffer:
- Identify the complaint noise.
- Disconnect the antenna lead in and plug the antenna sniffer (3) into the radio antenna socket.
- Turn up the radio volume.
- Search for the noise source (1) along the wiring harness (2).
