Vai tavs foršais supports kaut ko par šo var paskaidrot:
At such a power you will create huge harmonics, so filtering will be
needed. Harmonics are a natural product of the fundemental. So if I
transmit a signal at 100Mhz, it will produce harmonics at 200, 400,
800Mhzs and so on. Each step of these harmonics the power is reduced.
Coupled with the fact that TV signals require a wide bandwidth and
very high power, many MHz wide to fit it all in, otherwise it'll go
out as garbage! You can begin to see it's not as simple as first
imagined
