aaahhh . . . yes - "normal" chicken wire would indeed corrode fast.  I
wonder if copper or galvanized chicken wire is made?

Chicken wire will rot out fast,you don't want to do that. As for wire gauge,
it really doesn't matter, I think I'm running 18 gauge wire. I ran single
strand but that's just because that's what was on discount in a while spool.

I just made like big staples out of peaces of the wire to hold it down to
the ground. It took 2 years but finally they're disappearing in to the
ground. Just do what you can, if it's ground mounted length isn't critical
of the radials. In the air it is on the ground it's not. I have all kinds of
different lengths, most the recommended length of 30 feet for my antenna but
I have some longer some shorter and living in a trailer with metal skirting
around the bottom, I have that connected as one huge radial as well. I can't
say it made much noticeable difference with or without that.
