Bob,
I had the same experience. I was using bare 75 ohm TV hardline as a matching
section on my 160 Delta loop and it was partially buried. But after 2 years,
the outer jacket was almost gone when I had to dig it up. My soil is just
regular sandy dirt.
So my advice to anyone that wants to bury aluminum cable or wire is make
sure it is insulated or jacketed.

I have used solid #10 aluminum as radials buried 6" in alkaline soil. It
became badly corroded in 2 years; nearly disintegrated in spots. Not saying
it wouldn't be fine in other soils.

From some feedback on the aluminum coated steel, I am thinking about
trying some regular aluminum, 14 gauge. Anyone got a downside to this?
Price, weight, conductivity are good and little if any stretch. I will
use aluminum screws and nuts on the end terminations with No Ox. 73 Mike
