If you really think none of this is relevant they you do not understand how these transmission/reception systems work. It actually explains a lot.

I said it was irrelevant to whether or not the signal is transmitted via satellite.
It is, as that signal could be coming from another source.
Knowing that receiving angle of dish is very narrow and direction setting is very sensitive,
we have proof of the precise direction of the signal source.
To receive the signal from other source we should aim the dish in the direction of that other sourse.
Considering that no tower can be that tall, and no ballon can stay still in the sky, especially not for years,
we have proof evidence that signal comes from geostationary satellites.
That is the one of the possibilities.
FTFY.
No need to thank me.
LOL
You are right. There in deed is no need to thank you. :-)
This is why:
New Orleans is 30 degrees north.
If people want to receive signal from 91W GALAXY 17, they have to point their dishes 55 degrees up.
They know it because there is online calculator that shows them where they can see it from their location.
One of those calculators is "dishpointer.com".
For signal source to have elevation of 55 degrees from one mile south it has to be 1.43 miles high.
For another home at one mile to the west you would need another source at 1.43 miles up.
Another source, because previous one wouldn't be seen at the same azimuth from new location.
Why we don't see tons of such sources all over the USA?Now try to tell us that online calculators are "lies", and people "don't use them" to point their dishes.
Bear in mind that this forum is public and everyone, including those people, can read what would your answer be.
(You can use any calculator yourself, including DishPointer, to get the picture.
Play with locations and see where pointing directions intersect.
You can also see if their intersecting points can be consistent if the Earth was flat.
For example choose several cities at 90 degrees west at different latitudes.)
