Doug,

Thanks for the reply and photos.  I've had very poor results with active 
antennas unless it was placed at least as far away form trees as the 
height of the trees.  The only open area I have is a field between my 
house and the road where a 45 KV power lines runs.  When I get away from 
the tree line the power line noise gets worse.  The Clifton Labs antenna 
is very likely superior to any of my home brew active antennas so that 
is probably the difference.  Guess I'll have to stick with wires and 
loops unless I can get an active antenna out the top of a 75 foot tall 
tree behind the house.
