UHF does not actually penetrate better.
The shorter wave length allows it to 'reflect' off dense objects
thereby, getting into the nooks and crannies better than a longer wavelength.
That is why reception can very with as little as one or two steps in a different direction.
Those commercial airlines transmitting on AM, with that wide bandwidth, even get into my FM radio in the garage. Cheap filtering in the FM radio.
