What's a directional coupler?
What do they look like?
Don't bother answering those questions.

Why do the arguers, when caught in a tight corner, always escape to UHF
for
help from directional couplers?

There are NO directional couplers at HF.

So what is the element in my Bird Thruline then, and how does it work?

I'd dying to hear at what frequencies directional couplers suddenly begin to
"exist". A sudden change in the laws of Physics at some arbitary frequency
named by man.

(Most SWR meters I've seen use a directional coupler, by the way. Even the
cheap ones.)

I think we've got to the root of Reg's problem. Just like the last time he
raised this nonsense.
