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.

Also, I suggest that you check the feedpoint Z with a good antenna
analyzer right at the antenna. Depending on your soil conductivity, 35
ohms is pretty optimistic.
