Cable arrangement for active antenna combined with screen heater

摘要

A car rear window (1) heating element (3) has connecting leads (4) in which passive circuit elements are included in order to pass or block HF signals selectively to utilise the heating element (3) as a radio antenna. The connecting leads (4) for the power supply feed have integrated coils (6), with a capacitor (7) to block HF signal flow to the battery and bodywork. The RF output is at a connection point (10). The components are contained in heat-shrink sleeving on the cables.
