My mistake, I thought that the article was comparing a horizontal loop
with a dipole.

I have used an inverted V on top band and never saw the 7.5Kz bandwidth
problem or anything close to that. Still, I would prefer a vertical, but
that's another subject. W8JI apparently did not see the loop advantage
that you have.

hey Steve, yes, I did enjoy the article about verticals/beach, very
educational! BUT, in the same issue of QST another article "If you can
hang a full-size vertical loop, then hang a dipole" really made me roll my
eyes. While I have never done any modeling, 50 plus years of playing with
various antennas leaves me with the opposite conclusion. A loop is ALWAYS
better than a dipole in my experience. I wanted to spend some time on 160
some years back so I strung up a dipole at 110 ft with the resonant point
at 1840.00.... worked great.... all kinds of dx.... BUT the 2:1 swr points
were only 7.5 kz up and down... even with a tuner the antenna preformed
poorly beyond that. It was just un-satisfactory so i pulled it down and
replaced it with the 160 antenna I still use today. A full wave loop fed
at a lower corner, top at the same 110 ft point. I did have to tilt it 15
deg from the vertical to get it in the property lines but it works like a
bandit. It is quiet and broad banded: 2:1 is 1800 to 1890 and works well
over the whole frequency! I would NEVER replace it with a dipole. Well,
thats my 2 cents and I am sticking to it! lol, 73's Cort K4WI
