Thanks to everyone for their input on this issue - which is, ironically, about the continued viability of one of the basic, original "inputs" on Roku TVs: antenna TV (aka, the RF coaxial input).

"For now, the only way I can change channels on my TV is to use the "Manage Channels" setting on the main TV screen by using the pop-up on the left side of the screen. All of the local channels will show up and I can hover over the one I want to view and it will go to it."
Yes, accessing Manage Channels is central to getting OTA channels back imho.
In my case, addtional factors are involved:
1. It was necessary to access "Live TV" in left menu selection - as accessing "Manage Channels" from icon/tile yielded a blank channel list... so there were no channels (streaming or OTA) to manage.
2. So I accessed the "Live TV" menu selection in left column - or alternatively, accessed the "Live TV" sub-section from within the Roku TV (icon/tile/app). Accessing either one correlated with OTA channels re-populating the channel listing, along with streaming channels.
3. Once I was able to access "Manage Channels" with an actual listing of OTA and streaming channels, OTA channels have remained.

As I mentioned previously, one other method that correlates with return of OTA channels in the channel guide is to disconnect Internet.
This is a pointless fix, unless you want to periodically connect/re-connect.
But it was a sure fix, in my experience.

As some users have reported: I also have the persistent issue of sometimes not being able to change channels from within the channel listing. I can select a program on channel listing and get info about the program and/or channel, but clicking on an in-progress program in the listing does nothing.
So in that case, going back Home and starting over typically fixes the issue.
The 'problem' tends to occur primarily when first turning on TV and accessing the Live TV tile/icon.
Weird issue, but I've learned to be very careful and methodical when first accessing the Live TV tile/icon - it does seem that Roku OS can become 'confused' otherwise. As a former computer progammer, I recognize this behavior as problematic logic related to monitoring the real-time event loop... there are lots of things happening in real time on your television, and obviously, things can go wrong if your programming doesn't account for all possible events. :^)

There is at least one other thread dealing with the general set of issues related to inability of TVs running Roku OS 11.0.0.0, Build 4193 to tune OTA channels and list them in the channel guide:

In this thread, Macmanjimmy69 relayed another possible fix he had found on other forums:
"Goto TV Inputs setting and change icon from "Live TV" to "Antenna"... restart, change zip code (to another nearby) restart, scan channels, restart..."
May or may not work for you, but I did change the icon/tile and label for "Live TV" to antenna... just for my own satisfaction. It at least makes clear how I think of that icon: as a representation of the antenna input - to which Roku then chose, at some point in history, to add streaming channels.
The icon/tile represented the antenna TV input to begin with; Roku OS app should still respect that basic function of the television.
I now just label that icon/tile "TV" - it is stil the antenna TV input to me, even though Roku has moved on to emphasizing streaming channels... which, don't get me wrong, I also appreciate! The selection of free ad-supported streaming channels is great, as long as OTA selections are also still available.
Both, please!
