You are not required to use the antenna that Yurii has shown us.
It is an interesting unconventional design that is not intended to conserve space, but to demonstrate the use of a flat coplanar loop used as a driven element in a yagi antenna.
The main advantage of a loop fed array is that it is better than a conventional yagi at rejecting interference from other directions. Hams find it useful when working weak signal DX. I would imagine that it would have the same advantage for TV DXers and to reject multipath reflections.
It would certainly help reject co-channel and adjacent channel interference from another direction. We will probably be seeing more of that as a result of UHF Repack.
If your mind is closed to new ideas that don't agree with your old ideas, how can you learn anything new?
I didn't see any ads when I clicked on the link to Yurii's journal, but I did see the circuit board for the LNA.
If you can not measure it, you can not improve it.
