Thank you on1aag for your respons,
I see on that topic you suggest there are explaining how to build high gain antena, and there are not found for electronic circuitry for amplified receiving am/fm signal radio from car aerial that I want to.
Thank you tanveerriaz,
What you inform to me very useful. I found there is active antenna circuitry for AM/FM/SW with +9voltage source. How to implement it at my car with +12 - 13.8 voltage source ?
And at the car, power source get from battery or alternator that can generate noise signal then able to annoying radio signal receiving, how to suppressed this noise ?
Hi, I'm sure there used to be an antenna amplifier for the car from Maplin Electronics because some years ago i had one and i'm sure i bought it from them. I think Radio Shack (Tandy) also did one but i dont think they exist now, Tandy's that is.
