Re: fm transmitter connect antenna ?

1 mile is very good range. Usually the circuit design starves the FM power amp (high value collector resistors or small capacitance) in order to limit output power for regulatory (FCC) approvals.
The only time I know of that kind of range is tuning radio stations in my car I picked up a bingo hall announcer's wireless microphone. "Under the N fifty twoooooo" lol.
Using small FM transmitters is popular for outdoor parties, raves etc so everyone can tune in to the DJ.
