Would sky waves be suitable for transmission of TV signals of 60 MHz frequency ?

A signal to be transmitted through sky waves must have a frequency range of 1710 kHz to 40 MHz.,But, here the frequency of TV signals are 60 MHz which is beyond the required range (frequency range: there is a maximum frequency of EM waves called critical frequency, above which wave cannot reflect back).,So, sky waves will not be suitable for transmission of TV signals of 60 MHz frequency.,Important point: Sky wave propagation: These are the waves which are reflected back to the earth by ionosphere.Ionosphere is a layer of atmosphere having charged particles, ions and electrons and extended above 80 km – 300 km from the earth’s surface.
