Hi All,
I have got a theoretical problem:
if I considerably change the output pwr of any tx - sw or lf -
I have to readjust the matching equipment.
more pwr means less inductivity to readjust the resonance of the
aerial if the aerial is a dipole (sw) or a inv. L (lf).
but - more pwr the more capacity to readjust the resonance
if I use the TX-loop (lf; 70m long, 12m up and 2m above ground, two windings).
is it the charge caused by the E- or H-field "on the spot" (as ON7YD
wld put it)? If so, why have I to increase the impedance in one case and to
decrease it in the other?
does the reader have an answer or does he know where I can look up
the theorems? is there any theorem?
regards and tks in advc
