I recently acquired an Alpha Delta DX-A 160-75-40 meter sloper.
It is installed around 45 feet on my tower (had another sloper but the 75 meter portion just never would work).
Bandwidth (below 2.0:1 SWR) is pretty much good. 160 is about 80 kHz. Could adjust it more but haven't.
75 meters is around 1.4 mHz.
40 meters is good across the entire band.
Could be a bit more robust in the mounting scheme (take note of a W9INN Sloper construction sometime).
All in all, a good performer for the low bands. Won't compare to huge amounts of wire in the air, but if you don't have the height, acreage, etc., I would recommend getting one.
