If you can match a good antenna to the FM transmitter, the effect will be better.The transmission range depends on many factors. The true distance is based on the sensitivity of the receiver, antenna of the receiver, and the building and other obstructions, which are between the transmitter and receiver. And the distance will much more in countryside.
ATTENTION: Never power on the transmitter when an antenna is not connected!!!
