I saw UHF only.

> If you talk like external modulators than you may be right (I don't recall seeing those either). In general though we used to use VHF for broadcast in non-NTSC part of the world too. Obviously there wasn't much room in this band so only 12 channels were available for broadcast use on VHF. UHF was added later on and for a relatively long time TV sets had both bands. I /think/ VHF channels were still in use in this millenium.

"*Used to* use" ? "*Were* still in use" ? What do you use now?

Here in North America VHF channels are definitely still in use in this millenium, although with a few exceptions we switched from analog to digital ten years ago; according to Wikipedia Europe also still uses VHF, albeit on slightly different frequencies.

Am I missing something?

FWIW, over here RF modulators, cable and ATSC converters etc. with analog RF out almost always use channel 3 or 4, with a few UHF exceptions.
