Hi,

Take a look here:

It's the "wideband antenna.djvu" file. I translated the most
important details of the text into English.

car aerial amplifier problems

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.

TIA

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 ?

TIA

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.

Yes, I have seen some companies sell it, but I want to make it self.

you use power source get from radio +wire
use lm7809 for 12v to 9v.
use lowpass filter in powersuppy

Okay, thanks for your all response guys.
I will trying to assembled it now.
