[Elecraft] K3 Multi-Band antenna thoughts

[David Cutter]

Bill

DX Engineering stuff is very well made and I wonder if perhaps some of the 
difference between theirs and the Elecraft BL2 is more a question of size. 
I'm wondering if you could be getting the same amount of heat in each balun, 
but the huge bulk of the metal-encased 10kW DXE product simply absorbs all 
you can throw at it, whereas the little Elecraft unit is only 2.5% of that.

Your antenna sounds interesting.  I wonder what the swr is at the bottom of 
the feeder on each band.
