Ted,

My sense is that any gain in area from making the loop closer to ground 
will more than be eaten up by increased environmental losses. Bill 
Ashlock has suggested 6 feet as a minimum. My loop is more like 8-10 
feet above ground. It's probably also a good idea for keeping people and 
animals away from the loop while transmitting.
