[Elecraft] Good Low Horizontal Loops - questions

[Lloyd Lachow]

I could probably string a roughly circular 1K' loop on
my lot, through the trees, with an average height of
about 50'. Here's what I need to know, though:
when feeding the loop, is the loop broken, with one
side of the feedline going to each side? If so, is the
distance across that gap critical? What types of
feedlines would work - which would be best? Can I use
twinlead? Would I need a balun, an rf choke, or
whatever?
My rig is a K1 with KAT1, 40-30-20-15. Would one end
of the feedline go to the center conductor, and one to
the ring? Would I need counterpoises? Will the
feedline radiate? Is it ok if it does? 
My house is roughly in the center, so If the loop were
shorter, the feedline could be shorter (trees
everywhere).
And, perhaps most importantly: I'm now using a
longwire of about 200' that goes every which way, and
works very well - good reports all over Europe, down
to Central America, and domestically. Should I be
satisfied with that, and cease this endless restless
quest for gain? 
Wire antennas are about all that will pass the xyl
review here. 
All help appreciated, on or off the list, as I realize
much of this is very elementary to many of you.
73/72,
Lloyd, K3ESE
