At high frequencies radio waves take on the properties of light waves. They just bounce off of stuff rather than go through it. 3 and 4 GHz needs line-of-sight to really work well. The lower frequencies, such as VHF television, propagate much better through materials and depend a little less on line-of-sight. It would work better over longer distances.
