Dave,

Not sure if the chicken wire or the salt water swamp location would help. 
This isn't the typical electric field return problem solved with a lot of 
ground radials, etc. With a loop the magnetic field surrounding the lower 
conductor has to pass though the soil and exit to form a near-circular path. 
To reduce losses, other than raising the loop, the field has to to be 
re-directed. This is similar to the effect of mu-metal shielding in the 
audio spectrum. You don't really shield the magnetic field but force it to 
follow a highly permeable metal. I have a few ideas that I have not had the 
time to try out that follow the same reasoning.

This is a 1/2" copper pipe. I have a 'first' loop article that appeared in 
the March Lowdown covering a simple #12 50/50 loop that was much more 
effective than my verticals had been. I'm putting the final touches on my 
second loop article for the Lowdown that covers the details of all the loop 
conductors that I have tested plus a newer transmitter output stage and 
coupling info.

Not sure

Me Too!
