[Elecraft] 75ohm Impedance question K3S and Antenna side.

[David Gilbert]

Very true, and in fact due to those ground losses the feedpoint 
impedance might be higher ... and therefore provide a better "match" to 
the 75 CATV line than if it was 35 ohms.  The loss just shows up in the 
ground instead of in the UNUN (they aren't lossless), on the line, or in 
the rig tuner.

I agree with most of the comments here.  I'd try it first without the 
2:1 UNUN.
