Thanks for the answers. I even got a personal reply from someone with some
Pinot across the pond confirming the above.
No clear boundary, no differnce and it's OK to have the FS meter in the
shack. Now why can't I find out this quick and easy if the final in a Tx
is dissipative or non-dissipative to reflections?

You'll get different strength readings at different distances from the
antenna, and in the near and far fields. But they'll all stay in
proportion as you tune your linear, so it doesn't matter where you put
your meter. The only exception is that you need to put the meter far
enough away from the linear that it won't be responding to radiation
leakage from the linear itself, which could be coming from the tank
components or parts of the circuit ahead of it. You could check this by
seeing what your field strength meter indicates when the linear is
feeding a good dummy load. If it's a significant part of your reading
when driving an antenna, you need to move the meter.

I had a couple of reasons for asking. One was to find out more which I
have. I use a field strength meter in the shack which is in the near

a tuning aid for tuning my linear and wonder if I would see any

difference
it I placed it in the far field and remoted the reading to the shack?
tnx
