Talk:UHF television broadcasting

Severe Copy Edit requested
I got through a good chunk of this article, but not only does it need sources, it needs a severe copy edit. There are multiple issues, such as run on sentences and sentences that start with prepositions. I would fix the remainder but it seems like a task that I can't complete at this time. Any help is appreciated.
 * needs sources
 * run on sentences
 * grammar
 * prose
 * updated tense

 * I have added a refimprove tag. There is already a copyedit tag on . Are there other sections that need this work? ~Kvng (talk) 14:46, 17 August 2015 (UTC)

frequencies
The TV frequencies used in antenna size examples are the bottom of a 6MHz channel. For digital, the center probably makes more sense. For analog, the VSB carrier is, I believe, 1.25MHz above the bottom of the channel. Gah4 (talk) 13:12, 11 February 2020 (UTC)

KYMU
The article says that DTV stations are on UHF or upper VHF channels. I believe that until last year, when Seattle got KYMU on RF and PSIP channel 6. The usual antennas sold now for DTV don't cover lower VHF channels so well! Gah4 (talk) 23:40, 15 July 2020 (UTC)

designated 14–55, between 475–890 MHz
The article says designated 14–55, between 475–890 MHz. The usual channel spacing is 6MHz, so that must not have been 6MHz. Later on, it was 470MHz to 890MHz for 70 channels, 14 to 83. How were the channels at that time? (It isn't easy to change after some start broadcasting, and TV tuners are built.). Gah4 (talk) 17:41, 24 July 2020 (UTC)

importance tag
I do not believe the above tag belongs to this article as it is not exclusively about the United States. It presents a more world wide view, which may expand as more editors contribute. DieSwartzPunkt (talk) 15:25, 6 June 2012 (UTC)
 * As well as I know it, this doesn't say it is just for the US, but says how important it is to US users. There could be ones for other countries indicating other importances. Gah4 (talk) 01:10, 10 October 2021 (UTC)

Watertown NY not a UHF island
Watertown NY’s WWNY signed on in 1954 as WCNY channel 7. It was boxed in by other VHF signals from all four directions, and no other VHF allocations were possible. Watertown remained a one-station market until public station WNPE (now WPBS) channel 16 in 1971. 2600:4040:5D30:4800:3547:472F:E736:4636 (talk) 16:55, 11 September 2023 (UTC)

"while VHF channels are being retired."
This is no longer true. After the recent repack, a number of stations took the auction money, giving up their UHF channel and moved to VHF. A fair number moved to low VHF which tends to have reception problems because of higher levels of man-made noise and the susceptibility of ATSC 1.0 to interference from reflections (ghosts in analog terms).
