Mal,
I have wound a loading coil using decca 729 strands litz and another 2.5mm
teflon insulated wire one and compared results. On air measurements and
reports are identical, regardless of what theory dictates.
Am I going to have to send you a loading coil made from #12 copper and and
another with identical dimentions from #12 Litz to prove to you there is a
2x reduction in Rac? Assume you have a way to make these measurements? Using
on-air measurements as a way to measure a change less than 3db is not a
sound approach, especially if the A/B change can't be accomplished by simply
flipping a switch. This change in fact could be under 2db due to the
additional series resistance in the circuit added by soil loss.
Regards,
Bill A
