My property is 350 ft long by 60 ft wide, which is not too small in this part 
of the world.  Planning hassles have forced me to place my mast about 30 ft 
from the rear fence.  That means that I am limited to 30 ft radials on 3 
sides.  That would be classed as pretty pathetic by most people.

My attempts at top feeding in one form or another are intended to mitigate this 
disadvantage as much as I can.  I guess a lot of guys may be in similar 
positions.
