Yes, but the amplitude and phase relationship of current to
voltage can have any possible value and there are an infinite
number of possibilities. In the equation, Z = V/I, you cannot
determine Z unless you know BOTH V and I.

Why can't I measure the standing wave ratio as a ratio of power, ...

You need both voltage and current to determine power. Your design
senses only current.

Cecil is right. Also, the 100K implies 200V to get 2ma of LED current. The
1N914 won't hack that.
