[TowerTalk] Interesting development

[Big Don]

This effect might explain the phenomenon of "working someone on your dummy
load."
You may be just "working" your tribander 100-odd feet out in the yard,
while your e.g. tribander is doing the heavy lifting.  The dummy load is in
effect "stacked"
with the tribander....
