Let me restate my previous statement -- "Contrary to the belief of many,
a beam located at a lower level on the tower does not shield any top
loading in the form of other beams which are above that level." -- I
indeed did mean "shield", because that is the term used by many of the
"many".
I also agree with Tom that 160m current distribution could be altered
such by the low-mounted beam to be detrimental.
