OK. Perhaps here the problem lies....

I am looking at it like this:
I don't care what value is V, nor what value is I...
I care only how much power the antenna is radiating, and how much is
"reflected" back and sits on the plates, collectors, or drains and is wasted
as heat--develops itself on the feedline--radiates from other antenna
components--etc....

I am thinking the "directional coupler" is doing that action, and forcing
the amount of "forward" power to one LED (amount of power actually leaving
the antenna (allowing for losses)) and giving indication--and the
"reflected" to the other LED (the amount of power "wasted") and giving
indication...
I take for granted that when 'Z' of "output of xmtr" = coax = antenna input,
I see the "REF LED" at dark condition....

There WELL may be an error in my thinking and, the "thing" (frankenstein?) I
have constructed only "seems" to work... (kinda like time yanno grin)

Thanks for your patience Cecil....

Warmest regards,
John
