Yes, the difference between wood and concrete is significant -- concrete 
is a conductor, so it's going to provide some shielding. Glen owns an 
Alex loop that he uses QRP from hotel rooms, and it does work with wood 
frame construction. All the caveats about height apply. And even in wood 
frame construction there are wires.

Your points about contact resistance are well taken. Glen is a fine 
engineer who has been working in the space program, holds a dozen 
patents. He's studied the literature on loops, and is quite aware of 
these issues.
