[TowerTalk] staples for radials

[K2EK at aol.com]

Might there be a problem using steel staples over copper wire? Isn't  
there an opportunity for dissimilar metal corrosion?

I was wondering the exact same thing...

Wouldn't rusty baling wire staples (or coat hanger, etc) over bare copper 
radials create a field full of mixer diodes, creating a heap of spurious 
signals???

I am planning an 80 m plus 40m 4 square with a decent radial field.  Unlike 
my NY QTH, this place will require an occasional mowing.  Some kind of keeper 
will be needed.  Wisdom suggests be careful.  Any suggestions?
