I stumbled by this dirt by accident.
It has not been tried with DVB-T nor ATSC...

Earth-Moon-Earth (EME) propagation (Moonbounce)
-- [image] "The Arecibo Radio Telescope is the world's largest antenna ever 
used for EME DX"

Since 1953, radio amateurs have been experimenting with lunar communications 
by reflecting VHF and UHF signals off the moon. Moonbounce allows 
communication on Earth between any two points that can observe the moon at a 
common time.

Since the Moon's mean distance from the Earth is 239,000 miles, path losses 
are very high. It follows that a typical 240 dB total path loss places great 
demand on high gain receiving antennas, high power transmissions, and 
sensitive receiving systems. Even when all these factors are observed, the 
resulting signal level is often just above the noise.

Because of the low signal-to-noise ratio, as with amateur radio practice, 
EME signals can generally only be detected using narrow-band receiving 
systems. This means that the only aspect of the TV signal that could be 
detected is the field scan modulation (AM vision carrier). FM broadcast 
signals also feature wide frequency modulation, hence EME reception is 
generally not possible. Indeed, there are no published records of VHF/UHF 
EME amateur radio contacts using frequency modulation.

While not yet confirmed, the 305-metre Arecibo radio telescope may be 
capable of receiving weak viewable EME television pictures. Based on 
mathematical calculations assuming 60 dB antenna gain, FM broadcast EME 
reception may also be possible using the Arecibo dish antenna.
===========================

Has anyone attempted to 'moonbounce' or EME ATSC UHF band TV signals, in 
the
UHF band allocation?

There are a few problems.

A typical UHF TV-transmitter antenna will radiate only to radiation
angles very close to the horizontal plane, thus the communication is
possible only when the Moon is close to the horizon.

Looking at the situation from the Moon, communication is possible only
through transmitter sites close to the Earth's perimeter. There would
be multiple transmitters at the same channel (analog or digital), thus
causing interference to each other.

I would be quite surprised, if you could find a situation in which no
unwanted transmitters are illuminating the Moon and thus the signal
would be recoverable.
