Re: [TCML] Voltage Question

[Carl Noggle <cn@xxxxx>]

Hi--

To get more signal you could hook up the secondary to a NST.  The 
problem is, you will charge the whole secondary, which will contribute 
to the measured field, while in reality the secondary contributes in a 
graded manner.  Maybe if you charged the whole top load and secondary 
and took a measurement, then unhooked the TL from the sec, charged only 
the TL and measured it again, the average of the two might be fairly 
realistic.
