  • Possible car PC antenna solution

    I was talking to someone about factory head units and he mentioned how they use the same antenna for both AM and FM. I thought this sounded strange so I did a quick search on the net and found something quite interesting.

    It comments that car antennas are "untuned". Perhaps this is why the car antennas are crap on PC radio solutions? Normally antennas are supposed to be tuned to the frequency band that you're working with.

    There is a schematic on the page that might lead to a car antenna solution. Maybe someone could give it a try?

    Normally they have a standard size antenna that will work for AM and FM in cars. The manufactures took the lesser of three evils. Great fm, great am or crapy both. I would prefer an adjustable antenna to compensate for am and fm. Maybe some has already built one.
    And yes that could be the reason computer radios sound bad. But if so why do car stereos sound good?
    Um, I guess this is where you put something witty.WITTY

      Probably because the car stereos (HU) have this type of circuit built in, where like a D-Link radio does not. My suggestion is to hook the antenna up to this little circuit, and then connect that to your PC radio antenna input.

      To be honest, I don't have a clue about any of this stuff. Just trying to get some hmmm thinking going.
