The only thing to disagree with is that UHF cannot penetrate buildings better than VHF, the higher the frequency the more absorbtion by dense material so VHF would have a small edge. Sometimes rarely sporadic E propagation can increase the range of VHF and more commonly temperature/ humidity Inversion make a difference on VHF and UHF so it is not difficult to make contacts into the continent well over a hundred or two hundred miles from here in England
