A 160 horizontal loop up at least 40 feet
will lay down a strong signal out up to 1200 miles. As you go higher in
bands the better angle for Dx you get.
I had a 80 meter full size loop on St. Simons Island, GA and found that
although I was down slightly on DX I could easily work Europe and South
America on 75. On 40 it worked very well to Europe. On 20 to 10 I worked
6K QSOs on the IOTA frequencies in the early 1990's and led the SE ARRL
Division Low Power in the ARRL DX SSB in 1992.
The beauty was I could wrap the antenna around the evergreen trees. I
actually had to add 15 feet to the antenna to make a closed loop. I fed
this antenna with RG8X to a tuner.
On 160 the full wave loop was not a great Dx performer on 160 . If there is
room a short vertical or an inverted V might fill in the gap.
The two best articles on horizontal loops are The Loop Skywire by Dave
Fischer, W0MHS now W7FB in a late 1984 QST and the German Quad by a young
German college Student studying at Georgia Tech in a 1980 73 Magazine.
