How far(long) the transmitter cover? The transmission range depends on many factors. The true distance is based on the antenna installing height , antenna gain, using environment like building and other obstructions , sensitivity of the receiver, antenna of the receiver . Installing antenna more high and using in the countryside , the distance will much more far.
EXAMPLE 5W FM Transmitter use in the city and hometown:

Q3:How to choose antenna for transmitter?
Usually we need to check the maximum RF power that the antenna can afford, then use the antenna with transmitter that broadcasts at or below the antenna MAX.RF Power.
