I tried aluminum radials once, at my folk's house (my dad was a ham). He had an

pretty cheap. I dutifully laid out as much as I could wherever I could fit it. 
Lots of work. It seemed to help a bit but lasted only a few years because it 
corroded to nothing!


this is the challenge with aluminum, buried in the ground - if the soil chemistry is wrong, it disappears quickly.
