Morgan has i told you before, VHF can reflet waves on hills, metals, trees, etc. This has experimented many times by me and my hamradio friends, so no doubs with this.
UHF will not reflect on natural objects and will past thru walls, metals, windows and so on.
In your case i think that power of the transmitter is very important, especially if you are away from the transmitter, like the analog tv broadcast you mention to me. Also don´t forget that TV transmittions are wide, not like a two way transmitter that has a narrow bandwith.
The part of spectrum that best reflected in many experiment i have done in the past were btw 140 to 165 mhz.
