I tried aluminum radials once, at my folk's house (my dad was a ham). He had an 
18AVQ trapped vertical and I decided it would do better work radials. This was 
maybe 40 y ago. Somewhere, I'd come across a big coil of Al wire, maybe 8 ga, 
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!
