Of course not: but that isn't the point, nor the answer to my 
question.

Again:

what might be the difference, in your opinion, in the amount 
of harmonics transmitted between:

1) maxing out the link, and setting the loading to zero, and

2) tapping the antenna directly to the plate coil?

Remember, I'm (obviously) really, really stupid and am 
asking for your expert advice...

And here's a related question:

We think that the antenna impedance for the ARC-5s in 
normal use was somewhere in the vicinty of 5 to 12 ohms.

So, what was the plate impedance, that is, the impedance 
at the plate connection of a pair of 1625s, under normal 
conditions of voltage, current, and frequency?
