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.

Mike,
I have been using the 130' Cobra Ultralite Senior Multiband doublet style
antenna by < http://www.k1jek.com > for several years. I currently use it
with my K2/100 and KAT100. The antenna comes with 100' of twinlead which I
attach to a DX Engineering 10KW 4:1 balun (DXE-BAL-200-H11_C) at my window
with a short run of RG 213/U coax to the K2/100 and KAT100 Autotuner. I
tried using the Elecraft balun but it get very hot at 100W. The DX
Engineering balun never gets even warm.
The KAT100 indicates SWR match of 1:1 on most frequencies 160-10m with a
maximum of 1.3:1 to 1.5:1 toward a band edge or two. My antenna is only
25'
above ground suspended from and strung through pine trees. I routinely
operate at 50W on all bands and have no trouble being heard.
