Mike,
Mikes measurements:
>The current antenna current is .745A
>The tuning capacitance is 6410 pf
>The loop measures .165 mH
Sorry that I didn't pick up on this before but if the loop inductance
increased from .112 mH to .165 mh when you changed from N/S to E/W, without
lengthening the wire, you are definitely being effected to large degree by
the metal building. A good portion of your magnetic field is in the metal
and not in space where it needs to be to form a electomagnetic wave. The
field in the building could in fact cancel out most of the useable field
since the phasing might just be in an opposing direction!!
Hope you can rotate back to the N/S orientation asap and aren't too dizzy
from this musical loop-spinning! <G>
Bill
PS: Mike R: What about your metal fence? It didn't effect the loop current
but what about the field pattern?
