    Antenna interference for radio

    I am using my stock head unit because I like it and I bought a adapter for it so that I can directly plug in rca plugs to it with zero quality loss. Perfect for hooking up ipods and car pc's.

    Now the thing is that in my dash behind the radio is where I have a bunch of cables for the carpc. USB hubs, video cables for the xenarc, power cables etc. and these cables seem to GREATLY effect the antenna on the car. the radio reception qualilty deteriorates down to static on most of the weaker stations and the strongest signal stations vary.

    So what can I use to shield the antenna from this type of interference? Can someone link me to a product or idea?

    Thanks very much and yes, I did search "radio interference" and my question was not answered.

    Thanks

    edit: I would just like to clarify that it is not a noise on the radio. It is a weakening of the radio reception problem. So a filter would not work for me.

    Thats the setup that I have, although not installed yet.

    I was wondering the same thing, and was planning on wrapping as much of the cabling in foil or some sort of shielding.

    I have a "Center" speaker space on my 944 that was a single speaker solution that never had a speaker in it. The grill easily comes off and will house my USB hub with GPS BU-303, Bluetooth, 802.11G, ATI remote dongle & a card reader. The wiring will have to go directly behind the headunit ( JVC KD-LHX500 )..

    I also will be changing out my broken electric antenna. When I installed the HU, I had to splice the antenna wire, so I will try to find a double shielded antenna and re-attach antenna connector on HU.

    wrapping a cable in foil works?

    can anyone verify this is a viable solution?

    Well I had varying results using Aluminium (Aluminum for all you Americans out there ) foil. My final solution was getting a car antenna amp. Cheap. Only paid ~10 Euros , ~13 USD$

    Antenna cable. You might also wanna try and go with higher grade Antenna cables. It comes in different ratings, just like Copper Network cables.
