>Thanks, Bob.  Actually, I should have pointed out in my original post the loop was designed for max performance on 80 meters and above.  I have a separate 160 meter antenna system.  I was just agreeing that the BT1500 does not perform well on small antennas on 160.

>>Hmmm interesting Scott; don't hold me to this but your loop may be

>>get it up to 0.8 wave for 160 then maybe the palstar could handle it 
>>if the components have the range.  I have a friend who runs a BT1500 
>>on 160 at 1.5 kw but his loop is around 500 feet long.   I'm planning

>>balun on the high Z side to window line, balanced tuner and a 1:1 unun

>>how you define "work" but they won't say "my tuner is balanced" which
