We worked on developing an active anenna specifically for receiving LF 
and it just turned out to do pretty good on HF and MF as well. It will 
outperform any 200 foot piece of wire in the LF range. See the Sepember 
2001 QST for a construction article. The RF-590 is a really great LF 
receiver and it can make use of a good antenna. You will almost 
certainly have to spend some time trying out various ground arrangements 
to suppress power line harmonic noise.

You may want to look into a program called ARGO that is downloadable 
from that will enable you to look for signals with 
very narrow bandwidth filters.

Good luck.
