         For the past 12 years I have used 4 elevated radials (alone) 
about 20 feet high which are tapered to very near the ground at the 
feed point for about 20 feet.  There is a small fence 20 feet from 
the feed point.  This was all required by horses and riders in the 
field.  This 87 foot "T" antenna has worked very well.
         HOWEVER, if I had it to do over--I would change the taper 
from 20 feet at the radial ends down to 10 feet for the last 20 feet 
near the feed point.
         AND, if I didn't need to allow for the animals in the 
field--I would taper each entire radial from the feed point up to 20+ 
feet at their ends.
