It would be good if the focal length(F/D) was also shown for each antenna grid...!!!

There are no differences, except that the feed must be performed differently, to ensure a good impedance match. One can even build rectangular plate Yagi-Uda"s, and make the elements slot antenna elements. Also, a different feed is required for that.

I wonder why you make a radiator with a diameter of 537 mm, when you better use a parable from the trade....???!!!

For receiving, you can safely use either. Losses from using 75ohm would be negligible. Only for TX you want 50ohm.

,,,only on 50 Ohm impedance...!!!
