“Nobody needs an antenna anymore.”
No. Obviously you are right about antenna’s and electromagnetic waves.
The “analogue is dead” statement has to do with the image rather than the means of transmission.
But technically you are correct. If someone is using an antenna, then analogue is not completely dead.
The phrase simply means that audio and video are now presented digitally almost all of the time.
But perhaps your point was merely academic.
Of course it is the final image conversion, but the poster also coupled the analog is dead comment with specific mention of antennas. I am very familiar with the new TV standard, but my OTA interface is still an antenna. In the end, all this really doesn't matter. I was just wasting my time I guess because I've spent all my life working with antennas (so, it does end up being an academic point). :0) Thanks.
