As for the cables in your photograph, you can't judge the cable from the
cover, to misquote the old adage.
The pics show an installation done in the easiest/cheapest way for the
rigger. Not best practice especially in a low signal area. So I'd wonder
what other corners have been cut. Of course RF being a black art, you
can't guarantee how something will work by just the appearance.

Umm .. can I put me 'learned audio friend straight?.

RF is not a black art its just poorly understood. It obeys much the same
laws as every other thing in the universe...

yes, but you have to see the world as if you 5 meter eyes with very poor
resolution working at very long wavelengths...:-)

And a pretty poor optic nerve that leaks..

I recall some interesting physics experiments with a giant wax 'lens'
and two microwave transceivers..



However, the signal strength should have been measured at the actual TV
outlet and at the downlead.
