Simulation Environment: DVB-T/T2 Modulator, On Plains, and there's no baffle object around. The height of the tower: D*D=17H(D: Transmission Radius; H: Tower Height). The real transmission distance might be more or less, depending on the practical situation.

PS: The data is only for reference, helping the clients to make an initial program; The real distance is probably different from the theoretical value.
Suggested mode and corresponding bit rate
16QAM DVB-T (21MB) DVB-T2(27MB)
64QAM DVB-T (27MB) DVB-T2(35MB)"
The sample is a single-frequency point distance calculation, such as a multi-frequency point (broadband transmitter)
Example 1:
If the customer needs to transmit 29KM, use 16QAM modulation, and mix 5 transmitters with 5 frequency points, then a single frequency point 29KM needs a 350W transmitter, then 5 frequency points need a 350x5=1750W wideband transmitter.
Example 2:
If the customer needs to transmit 15KM, use 64QAM modulation, and mix 6 transmitters with one frequency point, then a single frequency point 15KM needs a 180W transmitter, then six frequency points need a 180x6=1080W wideband transmitter.
