I got the radioshark hoping to achieve AM and FM integration with Roadrunner (see
this plug-in. Well it works, but as everyone has determined, the radioshark's reception is horrible. I found
this antenna hack and I want to use this process to wire the radioshark to my car's antenna. Inside the radioshark is a single-wire FM antenna and an AM antenna coil. My question is this: does a car typically share the same antenna for AM and FM or is the external antenna for FM only (with AM using an internal coil of some sort)?
Also, how should I wire the antenna? The car's antenna connector is basically a coax cable, which means it has 2 conductors: an outer negative shield wire and an inner positive signal wire. Since the radioshark antenna only has one FM conductor - the antenna wire itself - how do I connect the two? My initial idea is to solder the radioshark's antenna wire to the car's antenna-coax cable's center. Or maybe the other way around (this woudl do nothing for AM, but I'm assuming that all radios use an internal coil-type AM antenna).
Basically I don't know anything about this and any help woudl be appreciated!
