Hello Alex, you are the person to talk to i hope. Can you explain in simple words (Jip and Janneke taal we say here in holland, childbooks) how does a transmitter signal actually gets to the receiver. I've know the transmitter sends out a signal, that is clear but what is see is that the receiver also sends out a signal (from the video antenna polarisation). Now usually when you send to "things" into each other you end up with a bang i mean when to cars for example drive in a straight line into each other you have a problem in the middle you don't end up with to cars at one end. So i hope you know what i mean and can explain it in simple words how the transmitter signal actually gets to the receiver after it has found the receiver "beam"
