Antenna theory

Hi thanks for the further replies i’ve now had a look through the above articles but didnt explain how the witnessing works unless i’ve missed it or not clever enough to understand it.

I am puzzled by this.

Why does an antenna need a witness for it to work ?

Or is this along the lines of;

“If a tree falls in the forest and no one is there, does it still make a sound?”
