[Lowfer] Worthwhile going to Shielded loop?

Paul, my thinking is that little is gained from a RX loop that large over 
say a 10ft diam  loop..... but you do get more signal for that long trek to 
the shack. In so far as the need to shield, it would depend on how you 
connect to the loop. I like to use a core with a single turn primary to a 
multiple-turn secondary in order to step up the Z. This theoretically allows 
the loop to 'float' relative to the E-field.
