I can indeed prove that the reciever in my dish has no physical means of transmitting, and only recieving. Considering I built the fucking thing from a Jcar kit. And no, im not brainwashed into not knowing how simple electronic recievers work. If I still had it i'd scan the circut diagram.
Not only that, the dish itself has NO OTHER reading equipment on it, it is literally JUST an aluminium rod screwed to a dish with 4 little 10mm screws, and two larger 30mm bolts holding it to the steel frame in the roof. These arent magic government screws either. Just your regular old 25cent bunnings solid steel screws.
Its totally illogical to think your dish is programmed to know where its pointed, when its pointed. Stop trying to use that crap as your basis for argument.. i mean... contradiction.
Also, on a perfectly flat earth you would still have many line of sight problems. Unless you want to deny the existance of mountains, hills, tall buildings, trees, etc. Towers arent all that tall by the way.
