A couple of other questions on this. I have 100 feet of coxial cable left from installing my Magnum Dyanalab ST-2 FM antenna. Can I use this cable as the basis for my "long wire" AM antenna implementation or is it the wrong guage and design? Is it insulated in some way that it will not pick up the signals as well as other wire and guages? It sure is easy to install on the outside of my home so it would be nice to use. Finally, I have heard that you can split the coax cable from my ST-2 so that a pair of leeds goes to the FM terminals on my tuner and a second pair goes to my AM terminals on my tuner. Supposedly it works very well and would save me a run of wire for AM. Causes no degrading of the FM signal either. Again, anyone have experience or comments on this?

Here is a great site, describing how AM antenna's work and how to build your own.
As long as this resides outside of your basement, you should get great reception. Good news is, you don't have to spend much money to get excellent results.
I should have responded to your question about using left over coax.
Since coax is shielded, it will not pick up AM signal, unless you used the shied as the pick up wire. Too complicated to use and a waste of material. Just use ordinary wire and follow the instruction at the link I provided.
Save the coax for another run to your TV or something that benefits.
