    HOWTO: Co-axial Splice

    There have been a lot of questions about utilizing the antenna on your car for other purposes. So I decided to write a howto on it.

    By splicing, you can use the antenna on your car with the D-Link FM radio (and others). You can also use it with a VCR to watch broadcast television.

    First, you'll need these. A wire cutter, electrical tape, and something to splice it to. I chose a typical co-ax cable that can be used with a VCR.




    Cut the end off the antenna in your car, and off the cable, stripping a good amount of wire. You'll notice that there is an inner wire, and then an outside area of wires. In between is somewhat of a foamy pad.



    Peel the outer wire back from the pad. Then, strip the pad off, exposing the wire in the middle. Jam the two inner wires into the pad of the opposing wires, this way, the inner wire sort of slides into the pad of the other, on both sides. Make sure you stripped off enough of the pad on both ends to get a good hold, and also make sure that the inner wire is going straight. On one end, the inner wire was weak for me and bent, so I cut it off and pushed the stronger of the two into the other one.




    Finally, mesh the outer wiring together, make sure that the inner wire and outer wire never touch, or reception will be very poor. Then, wrap it up good with electrical tape, and try it out!




    Enjoy!

    Don't do something like this for your high current (battery) leads. You'll be asking for blown fuses or a fire!

    Since this is a low power connection, it's safe enough to take this approach. On the other hand, you should be able to solder on a rca or F connector, rather than relying on a purely mechanical bond. Also, to avoid cutting any factory wires, you can buy an antenna extension and do all your cutting and splicing there.

    Yes I recommend getting a car antenna extension and cutting that. if you already screwed it up, you should know how to splice it back on

    You could also just buy 2 connectors (crimp or cramp) and a female to female thing.. no soldiering , allot nicer and more reliable....

    Question is though.. will it work with TV ? signal from TV station must be very strong to be able to get reception with a small antenna like the ones on cars .... Maybe a booster would help .....

    I think you cant do that with any car either.. like newer BMW's have this powered antenna in the left C pillar ( i know 5 series has two .. both left and right of the rear C pillars) these are powered and filtered , doubt any TV freq will pass trough that..... although i hope so hehe

    You see TVs with tiny little antennas on them all the time. The reception on the car should be as clear as FM radio. Especially since it's broadcasted from the same areas (usually)

    Thats true , for me at least you have to move around to get good signal and if you walk around you get it and loose it (good picture)...with those small antennas , guess transmitters are too far away from where i am at , its a good think im going to move soon in a couple of months , should be really close to them then.


    I admire your tinker skillz though hehe , quite good , looks pretty clean..
