What is your loading on the coil? How many turns? Schematic?

I've seen this page many times, but I lack a little of those details. I 
want to get a little more details so I get a better feeling of what it 

As I want a broadband H-field antenna, I know that I need to do 
resistive loading, but what is a suitable value?

I know that there is a benefit in putting a E-field shield on it, but be 
careful not to close it as that would cause it to block H-fields.

Cooking up a low-noise amplifier for these frequencies seems relatively 
simple, but it is always nice to see what others have done.
