Buzz,

If you can find insulated #12 electrical solid wire it works great and 
handles well even with frequent hits with weed wackers here.  One 
advantage of using insulate wire is that the velocity factor of the wire 
on ground or (ROG) allows for shorter lengths.  This is important if you 
have limited yard space.  I use large galvanized nails (spikes) at the 
far ends by wrapping the insulated wire around the nail and driving it 
into the ground. Only the insulation comes in contact with the nail or 
the ground itself.  In such a circumstance 90 foot long ROG's, if you 
have enough of them, should work well for you.  There is no advantage 
for a ROG to be a 1/4 wavelength over a more manageable shorter ROG 
length.  The real advantage is with the extra wires is put in as many 
shorties 40-60 footers  between the longer ones.  This is said to 
improve performance and efficiency of a vertical.
