    • A combined antenna system used for both vehicles and structures, whereby a satellite antenna is placed concentrically around a conventional mast antenna that can be used for both conventional FM radio and also terrestrial retransmission of the satellite broadcast signals. The combined antenna system, in a vehicle implementation, is configured to use only the one hole created in the vehicle manufacturing process, thereby preventing the necessity of drilling a second hole for the satellite antenna, which alleviates deterioration of the vehicle's body. Additionally, because the combined antenna system can be advantageously placed, a shorter RF cable connecting it to a receiver box can be implemented than otherwise would be the case for a satellite antenna located on a window or roof of a vehicle. In an alternative embodiment, the satellite antenna can be mounted on either a fixed or retractable terrestrial antenna, thereby raising the satellite antenna to a higher elevation with respect to any obstacles on the vehicle or structure.
    • 一种用于车辆和结构的组合天线系统,由此将卫星天线同心地放置在传统的桅杆天线周围,可以用于传统的FM无线电以及卫星广播信号的地面重传。 在车辆实施中的组合天线系统被构造成仅使用在车辆制造过程中产生的一个孔,从而防止钻孔用于卫星天线的必要性,这减轻了车身的劣化。 另外,由于可以有利地组合组合的天线系统,所以可以实现将其连接到接收机盒的较短的RF电缆,而不是位于车辆的窗户或屋顶上的卫星天线的情况。 在替代实施例中,卫星天线可以安装在固定或可收缩的地面天线上,从而相对于车辆或结构上的任何障碍物将卫星天线升高到更高的高度。
