I like the first users comments:
"Having a rotating antenna was not the solution because
with today's digital tuners, every time you rotate the
Antenna, you must rescan your channels."
I guess he doesn't know how to manually add channels.
with current Samsung so called "Smart TV's" it's not
possible to add a channel. I have confirmation from Samsung.
Sigh. I've been told to avoid anything called amazing, magic,
miracle, plus, super, and such. I guess I now have to add smart to
the banned list.
I just checked a Visio VX240M TV:

It starts out by skipping all channels and sub-channels. You can then
go down the shopping list of channels and select which ones to NOT
skip. Kinda backwards, but easy enough. The TV also has a "limited
scan" which allows the user to set channel areas to re-scan complete
with limiting the scan to digital, analog, or both.
I have a Samsung TV at home. I'll see what it can do later tonite.

USUALLY you can use the remote to select the physical channel and
the TV will tune to the first virtual channel on that frequency.
This is the preferred way the US government would like it to work.
Channel up/down will then tune the sub-channels.
I don;t yet have confirmation that an unscanned channel works
that way, but I think it will.
I have a TV tuner that will not work that way at all. It reports
the actual center frequency in MHz of the scanned channels, not
the physical channel, but you need the physical channel to add
a single channel. You basically "scan" the physical channel and
add. This "stupid" $1000 tuner won;t even update the display
when entering a channel digit. The on-screen display shows the
remote entered digit. The display on the tuner does not.
A CECB I have allows one to add "scanned" channels to the
existing scan.
Nice mess. In the daze of analog TV VSB (vestigial sideband), the
frequency of a TV channel was by the carrier frequency. This worked
because the signal was asymmetrical. Symmetrical modulation schemes,
such as FM, used the center frequency. SSB continued to use the
carrier frequency. Meanwhile, the FCC uses the center frequency for
most everything. Along came DTV, without a carrier frequency, so it
was decided to use the center frequency. That generally satisfied the
tech types.
However, the station owners wanted to retain their old channel
designators, even if the channel frequency was quite different. This
was allegedly to avoid listener confusion, but did quite the opposite.
I was told that it was temporary, but that doesn't seem to be
happening. The best laid plans...
One way to avoid having to deal with two sets of channel numbers would
be to replace the real OTA channel number with that channels center
frequency. That's apparently what was done in your expensive tuner.
Whether the GUM (great unwashed masses) could handle the concept is
debatable. They certainly are having problems with todays virtual
channel system.
Another proposal that came and went was to replace the virtual
channels with the stations call letters. This probably would have
worked with an internet connected TV that could search a suitable
database. However, the present system was thrown together before most
everyone had internet available, so that went nowhere.
