Am I going to have to send you a loading coil made from #12 copper and and
Bill. Try HW #12 pure copper tube, not the alloy mix you get these days for
commercial wiring and plumbing, even better SPT (silver plated tube tube)
Gold plate tube even better, very low RAC. These are all easy to solder and
although hard to get out perform all other varieties, available in all sizes
from diameters barely visible to sizes that need a fork lift to move about.
73 de G3KEV
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.

Bill A
