Question

What is the most suitable frequency band for receiving wireless electromagnetic energy?​

Answer 1

Under normal ionospheric conditions 40 MHz is the highest-frequency radio wave that can be reflected from the ionosphere. In order to accommodate the large band width of transmitted signals, television frequencies are necessarily higher than 40 MHz.
