Hi, So my car has no other option than an FM Transmitter. Replacing the head unit/stereo isn't an option. My FM arial is in the boot of the car, and I have cigerette ports there. I plan to run a long AUX cable from the boot, to the front of the car. This way the FM Transmitter will be as close as possible to the arial. 1. Is there any point building my own and making my own arial? Like this one 2. Does the signal not matter as much because I will never have a strong signal than a "real" radio station? I am in the Sydney CBD area, so there are lots of frequencies to contend with.
