I think you have the characteristics of vhf and uhf backwards. Vhf is less sensitive to obstacles and uhf requires direct line of sight, which is why the military uses it for aviation. The higher the frequency the less distance and more attenuation there is, thus the higher uhf will attenuate faster.
