Nope, radios are shit. Trust me. My day job is space radios, which are about 1000x easier to talk to (no mountains in the sky). Terrestrial radios are much more fun for all the problems they have.
IRL wouldn't simply elevating the ratio with your arm suffice in situations where microterrain is blocking the signal? If that's the case then I suppose an animation could be implemented on ACRE to represent this.
