[Elecraft] K3/100 into DX-CC antenna (HI-SWR)

[Jay Krishna]

Sorry for the multiple emails; on more careful checking, I found that the SWR is nice and low on 40, 15 and 10. High (3+) on 20 and 80, so I must have some mismatch on just 20 and 80.

Hi all,
 
Just spent the day putting up a multi-band DX-CC (fan dipole, 80-10M) in an inverted V configuration. Unfortunately, I could not get the center mast extended beyond 20 feet, with one end up ~9 feet from ground, the other, ~5 feet from ground. I am seeing HI-SWR on all bands. Any suggestions on what might be the issue? I was able to get decent SWR with my old 20M monoband dipole, 30 feet up.
 
I have heard that the DX-CC is sensitive to height above ground, and am concerned that 20 feet might be too low. On the other hand, I was hoping it will at least tune well on 20 M at that height, if not all the bands...
 
Appreciate any ideas/suggestions. I don't have an ATU in my K3/100, and was hoping a multi-band fan-dipole like the DX-CC would work well without need for an ATU.
