Antenna system using antenna base impedance transforming means

摘要: An antenna system is disclosed for plural band radio receivers having a common antenna. The especially adapted AM/FM automobile broadcast and may be used with CB transceiver tri-band impedance transforming means provided at the base of single transmission line or lead-in cable extends from to receiver. has high input AM FM bands relatively low output minimize signal loss in includes field effect transistor source configuration are produce substantially 100% voltage degeneration both signals. also useful avoid need alignment trimmer after installation on automobile.
