Hi OM,

Solder is for weather sealing an already conductive join. Those who
think of the solder as conductor then extend its resistive qualities
into the equation (ignoring the massive surface area involved). If
their solder jobs melt, it is only positive proof of the poor surface
preparation, and/or subsequent oxidation following a poor solder job.

Mike's 7 Meter diameter 40M loop hardly fits into the "mag loop"
genre. The coupling loop comes closer, but then it has the advantage
of being near the larger element which offloads the current demand.

Whoops! Typo alert! before we get too far, that is a 7.3 meter
circumfrence, not diameter. My bad. A 7.3 meter diameter loop would be
something indeed! And wouldn't work for anything higher than 6.5 mHz 8^)
