Default Open Loop aka Dipole bent into a square

I've got an update on my antenna experiment. I decided to buy a new
tuner, the MFJ 902H to see if that would help. It was priced low
enough and had a built in balun. I tested it out using my SWR
analyzer and this tuner was able to find matching points in the 80,
40, 30, 20, 17, 15, 12, and 10 meter bands. I did try to find a
matching point on 160 meters but wasn't able to do so which is OK,
since I've never worked 160 and the manual says not to try it on 160
anyway.

=========================
You highly likely find a matching point for the 160 m band when you
extend the twin feeder . The extension length to be such that from any
end of the dipole to the matching unit the total length is roughly 1 or
3 or 5 etc quarter wavelengths .Any part of that feeder which is inside
the shack can be coiled -up (kept away from a metal clad area).
