To know the transmitter:

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.

Below are the approximate range of different power FM Transmitters. ( The range is radius,The following distance is bassed on the antenna . )

50W TV Transmitter :3M ~10KM

100W TV Ttransmitter : 5KM ~ 15KM

300~500W TV Transmitter : 10KM ~20KM

1KW FM Transmitter : 15KM ~ 25KM

3KW FM Transmitter : 30KM ~40KM

TV-VHF-5KW:with the 4 Bay DV1 antenna:45KM

TV-VHF-10KW:with the Slot antenna:80KM

TV-UHF-5KW:with the Slot antenna:45KM
