I'm at a Q of about 200 with both the Litz cable and 1/2" cu pipe. The soil 
loss at the moment is about .22 ohms and probablay won't improve more than a 
few 100ths. Therefore the limiting Q would be under 500 even if the 
conductor had a 0 ohm Rac. This wouldn't pose much of a handicap for CW 
operation - nothing like the Qs in the thousands that the guys operating 
loops in the HF Ham bands experience.
