<p>An antenna arrangement (30) for a frequency modulated modulator that intentionally modulates and transmits a source signal to a frequency modulated radio receiver (28) in a vehicle (50) can include a portable audio source (32 or 34), a frequency modulator (10) coupled to the audio source, a coaxial transmission line (23) coupled to the frequency modulator, and a frequency modulated antenna (24) coupled to the coaxial transmission line where the coaxial transmission line is of sufficient length to enable the placement of the frequency modulated antenna substantially close to a frequency modulated radio receive antenna (26) coupled to the frequency modulated radio receiver in the vehicle. The portable audio source and the frequency modulator can be co- located in a single unit. The portable audio source can be a satellite radio receiver or a portable digital music player and recording device.</p>
