VLF submarine communication – Different frequency.. Different characteristics..
Un-Intentional Radiator – Is exactly that. Not intended to emit RF and not a part of an antenna system..
As for the Talking House/I A.M. system..
If a coax is balanced at both ends properly, it will not emit RF. The shield is RF isolated at the antenna end or it couldn’t be a balanced unit and do its job. Re: Balun or Phasing Harness. If it wasn’t balanced, no power would reach the other end and it would spew RF recklessly everywhere. The RF is controlled or contained until it reaches the antenna, which is the intentional radiator..
Why is this so hard to undrestand? It’s a typical antenna system that’s been used for decades! Obviously the engineers at Talking House/I A.M. figured out a design that contains the RF within the coax and isolates it at the antenna end to avoid the coax from becoming part of the antenna, giving it some usage flexibility for realitors. It was designed to sell houses with the antenna sitting on the ground out in the lawn or a inside floor of a room, not stuck 30′ in the air with a ground wire running from it, conveniently calling it a lightining protection ground! Of course, by adding the wire to it is going to make it more efficient and break the rules.. Duh! People abused it and now it’s not around any more..
