I'm building my first coil, medium to largeish, and will probably have
to run it outdoors, since I just don't have a spot indoors that seems
safe.  The soil where I live (northeast PA) is loaded with rocks, and no
way will I ever drive an 8 foot rod into the ground.  Would two or more
4 foot rods do?  I have serious doubts I'll even be able to drive in 4
foot rods.  If not, how about a bunch of 2 foot rods spread out and tied
together with heavy cable?
