Are the channels any good? Living in a high rise in Atlanta I could get 100+ OTA digital channels but they mostly sucked. What was interesting was the 4 or 5 channels I could get on Analog though, which I assume were some sort of pirate situation. All random Asian language programming.
I haven't lived in Southern California for about twenty years now so I can't speak to the current stations but in the 90s and early 00s I recall a lot of the UHF stations were foreign language. The English-language stations mostly aired reruns. So overall the plethora of stations wasn't all that attractive to me personally but the number was impressive.
Looking at the channel listings, there really is a huge amount of foreign language content in LA in a wide number of languages. Today is has to be more than it was in the 1990s because ATSC can fit multiple channels in the bandwidth taken by NTSC.
I'd contrast that to the Syracuse and Binghamton markets which I can both get most of the stations reliably where there are no foreign language channels but quite a few that show reruns of shows like Columbo, Farscape, That 70's show and such as well as news from the BBC and Japan.
and I can receive it indoors with rabbit ears in an old house which is full of little nails that interfere with radio. (Usually I use a small outdoor antenna, though it is hard to watch broadcast TV now that there is FAST.) People on the other side of Lake Erie in Canada watch for it DX when tropospheric conditions are favorable, on some of those days our repeater opens up an I can talk to them.
