Quoting Thrax

1. Known as the "Decimeter band," UHF has a particularly long wavelength and can easily penetrate the walls of homes and obstructions (Buildings, trees, freeways, etc).

I understand what you are saying, but it's the shorter wavelength (higher frequency) signals that have more energy and penetration capability. UHF was a big improvement over the old standard TV range and it was (revealing my age ), once-upon-a-time, a special feature on a TV set.

EDIT ADDED: BTW- Well Done, Thrax.
