  Q: What are the procedures and considerations for fitting and maintaining antennas on Volvo S70?

  A:

  On S70 and C70 models, different types of aerial can be installed as standard or optional equipment, depending on model and market usually on the left-hand rear wing, access being obtained by removal of left-hand side trim panel in the boot. Removal consists of unclipping and disconnecting of the wiring as required and then removing the retaining screws for electric aerials or the nut at the aerial base for manual aerials, although no specific removal and refitting procedures were available at the time of writing. In V70 models the aerial takes the form of a wire filament built into the rear window glass on the left hand side working with a signal booster mounted behind the trim panel under the rear window, small breaks in the glass filament may be repairable with special metallic paste but specialist help is recommended for the best results. For aerial breakage or poor audio quality then consultation with a Volvo dealer or audio equipment specialist is advised as many aerial problems have their origins in poor connections, including electrical faults. It is important to inspect the aerial wiring plugs at the aerial and at the rear of the radio and this may involve removal of the radio. Some aerials rely on a good earth connection between aerial mounting and the car body, so if needed, the aerial should be taken off to clean the aerial connection point. In the case of suspected earth faults it may be necessary to solder a wire to the aerial and connect it to a known good earth point. In addition, the aerial wiring could be broken or shorted at any point along its length which can be checked by connecting suitable lengths of wire to each end of the aerial lead and testing for continuity using an ohmmeter, any reading other than infinity should be a good continuity test.
