[Elecraft] Sloping Terrain vs Feedline Losses

Ted …

I think you are overstating the coax losses.   Even stock RG-11 should be perhaps 0.3 dB/100ft on 80 meters - around 1.5 dB for the 500 ft. run.  

Even so, I would probably gravitate toward the closer location.  With the elevated radials, the effects of the ground conductivity should be minimal.   Not sure if ON4UNs data assume elevated radials or many on-ground radials.  It could be that his estimate of the sloping ground advantage is for the later.   With the closer location, you will have perhaps 1 dB stronger signal in all directions because of the lower feedline loss.
