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? -- 73 Hank WD5JFR "Roy Lewallen" wrote in message ... 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. Roy Lewallen, W7EL Henry Kolesnik wrote: 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 fied as 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 |
