Paul,
It really doesn't matter to much how you prepare or fix the corners. I
have used free floating and fastened down tight. If they are in the trees
sooner of later the wire will snap regardless of how you have the corners
prepared. The alpha-delta cin insulator from Radio Works $1.50 are very good
one to consider using.

Now that we have heard all the benefits of various loop antennas, I
have a question about the physical part of the antenna. I am planning
on erecting an 80 meter or perhaps 160 meter square loop antenna. The
question is how have you fixed the corners of your loop antenna? Can
the antenna wire move in the insulator so as to equalize the force on
each side? Or is the insulator in the corner fastened tightly to the
antenna wire? Also, what type of insulators are your using in the
corners? Ceramic compression? Glass, Other type ceramic? Anyone using
plastic insulators?
