>higher output electricity for higher frequency signals
Now you really must be an expert … LOL
Please, stop it already – those who actually understand math & physics know that you're talking out of your ass.
If you'd ever done it for yourself then you'd know … for one example, one can compute parameters of the ionosphere by measuring GPS signals.
One can compute/estimate earthquake slip and also aseismic slip from GPS measurements where there's not a single tower around.
Please stop.
